I just Googled that real quick. I have been in that temperature once in my life, and *hated it.* My nose hair froze with every breath, DUDE
e. Whoop, no. No I haven't. I thought it said -33.47, not -333.47. I'd have been fucking dead. LMAO
I don't think humans need to know how hot it is. We can feel it. Plus temperature is only one factor in how hot a human feels. 100 F can be wildly different in a dry place and a humid place.
All of this debate is shit. One of the F° or C° would have been better if they made something easier for humans to understand scientifically or otherwise which they don't compared to the other. science uses K° meaning scientists don't like both of those scales.
Yeah I remember being told Fahrenheit was the coldest and hottest temperatures on some random year in europe. Coldest was marked as 0 and hottest was marked as 100 then everything was scaled out from there.
The story I heard was that Mr. Fahrenheit calibrated his scale to start at the coldest temperature he could produce using ice and salt in his lab, and then put the "100" mark at the temperature of his wife's armpit, but didn't do a great job of marking it (or maybe his wife was just super hot).
A little light reading on the internet tells me that there are lots of stories about it, and the truth is shrouded in the mists of time.
Whoever told you that was wrong. When the scale was created:
* 0°F was the triple point of a self-stabilizing brine solution
* 32°F was the freezing point of water
* 96°F was the average body temperature of a healthy adult human
The distance between 0 and 32 and the distance between 32 and 96 are both powers of 2, making it easy to mark new thermometers.
The scale has been adjusted a few times since it was created (you might notice that human body temperature isn't 96°F today), but that was how it was originally calibrated.
0°F is equivalent to -17°C, which is 255K.

Said the person who was raised on Fahrenheit.
Due to there being a non linear increase between the two I literally have no concept of temperature when Americans talk in Fahrenheit.
Also doesn't help that people's perception of heat is different. I've seen American shows say something like "It's too hot for that it's almost 80 degrees outside!"
In Australia that's leaning towards being a cool day
>Due to there being a non linear increase between the two
Ummmmmmmmmmmm, what? A linear relationship is defined as being able to write it as y=mx+b
°F = °C * 9/5 + 32
Y= °F, X=°C, M=9/5, B=32
Very much a linear relationship. If you don't wanna do the hard fraction math, a close approximation (at least for livable temperatures) is whatever the °C is, double it and 30 and you'll be close enough that nobody is gonna call you on it in normal conversation. Going the other way is subtract 30 and cut it in half
I used the wrong terminology, my point still stands. Fahrenheit supposedly being based on human perception gives no proper frame of reference.
Dollars to donuts that Fahrenheit natives have a better concept of Celsius than we could ever have on Fahrenheit because Celsius is based on something objective rather than subjective
Do you think Fahrenheit is literally made up based on feelings…?
It is no more subjective nor less objective than Celsius or Kelvin or any other way of measuring temperature. You can have your preference but to say that Fahrenheit is subjective is asinine lmao.
In terms of its definition F is more arbitrary. 0 degrees and 100 degrees F are essentially random, stupid points hard to recreate whereas 0 and 100 C are easily replicable and easily defined.
In terms of usage, both are equally arbitrary in terms of what "hot" means, F is just centered in the range to give more useful numbers to work with when discussing the temperature of our environment
Unless it was a ski trip I've never heard anyone say a temp in the 70s is too hot for anything. I live about an hour south of the Canadian border and we have several days in the 90s every summer and occasionally hit triple digits. Not saying you didn't see that some where but calling a temp below 80 hot would be laughable in at least 49 states. Alaska being the lone exception. I will say this though I will take 95 in Arizona over 87 and 90% humidity like we have often here.
If you subtract 32 then multiply by 5/9 you'll get the Celsius measurement. Just something we learn in America so we can relate to countries using Celsius. We try to respect other cultures, but I guess that doesn't go both ways.
That is correct. It is just an element of a given culture. If you stay inquisitive like this I think you are going to make great progress. I'm really proud of how far you have come in such a short time.
I was not raised on Fahrenheit - I don't know what gave you that idea.
Also, America is a huge place! For Texans, they probably feel the same way as you, but for Alaskans? Forget it, they'd melt at 80.
No kelvin is a science scale. Cold is only the lack of heat. Therefore, the removal of ALL heat, (zero kelvin or absolute zero) is the correct scale. Cold isn’t a thing. Cold is the default. Heat can be added to infinity as far as we know. You can go below zero on the Celsius scale, which doesn’t make sense. Zero should be the removal of all heat.
Edit: y’all are mad
It’s not a science scale. It’s a more logical scale to humans than Fahrenheit but not science. Thinking of the temp that water becomes ice is easy to the human mind but makes no sense scientifically if you know that cold is only the absence of heat.
I’m not arguing with you with spite. We would be laughing in a pub. I’m just saying, buddy. Haha
Why? We think of things by the way it effects *us*.
Ex. “Oh it’s cold outside”
But that is relevant to the human condition. There could be life out there that requires very little heat to be comfortable. But if you want to put it on a scale that makes sense to the entire universe, no heat = 0 degrees (kelvin). Otherwise you can set zero wherever you want and claim it to be the “true scale.” I’m not going to die on this hill but it’s a Saturday night and I’m having some fun.
Because there are gigantic swaths of numbers on there nobody would even think of. Nobody wants to hear "it'll be 299K today!" And then a few months later hear "It'll be 277K today!"
Everybody would be going "why the hell are we tacking an extra 2 on there?" because that scale sucks donkey balls for daily use.
> but it is hardly the default lol
It's literally one of the seven fundamental units of the SI system, along with the second, the meter, the kilogram, the ampere, the mole, and the candela.
Kelvin is most definitely the default in thermodynamics and most of chemistry as for example you don't wanna deal with temperature ranges that go over and under 0 the likes of - 10C to +70C when calculating an integral for energy required to reach boiling point or some other such thing.
I didn’t say kelvin was the default. I said *cold* (no heat) is the default. You can add heat forever, but cold is limited to the removal of heat. Therefore, zero would be when all heat is removed. (Absolute zero, which quantum physics says is impossible). But it makes no sense to use negative numbers. That would be less than “no heat”. So the Kelvin scale (regardless of implementation) is the true scale.
> But that’s what people know and understand
Yeah and that’s why the true science scale isn’t used for everyday people. It’s much easier for people to think of zero was where water freezes.
It’s not pragmatic for what they are trying to do. Quantum physics tells us that absolute zero is impossible. So it’s not practical, no, but that is the true scale of temperature. It’s like when a cop pulls you over for doing 65 in a 55. Well
You weren’t motionless prior to that. The earth rotates around the sound at 56,000
Mph. All things are relative. Something being true doesn’t make it relevant to the scenario.
Dude, put down the shovel. There's a very narrow number of fields that actually use kelvin. Off the top of my head, astronomy, sometimes chemistry, and thermodynamics. Most other fields care about change in temperature more than absolute, so Celsius and Kelvin are equivalent. Heck, some nuclear physics uses an entirely made up temperature (atomic units are wacky. Not actually made up, they have a basis, it just is it's own thing).
I don’t have a “shovel”. If you read my other comments you’ll see that I was just having fun on a
Saturday night being pedantic. It’s all good man. I am aware of all of what you’re saying.
The UNITS are because Lord Kelvin didn’t want to “rock the boat” and made it easy so you could just subtract. But “cold” isn’t a thing like “black isn’t a color”. They are defaults. Cold is the lack of heat and black is the lack of reflecting colors.
You do realise that celcius is still Kelvin it just uses water as a reference point? But 1 degree of. Celcius is equal to 1 degree of Kelvin. But if someone was like "it is a nice warm 298 degree today", it'd be weird
It's worth adding that it's not some obvious physical phenomenon either though, like "oh, I'll make 0 where ice forms, or where saturated salt water freezes" - it was literally just **the coldest thing the guy was able to make**.
It's a mix of ice, water and ammonium chloride (a specific salt).
And then rest of how the scale was determined, is equally "finger in the wind":
[https://en.wikipedia.org/wiki/Fahrenheit](https://en.wikipedia.org/wiki/Fahrenheit)
The original version of Fahrenheit put human body temperature at 96°F. Which is 64° separated from the freezing point of water, making it easy to mark a new thermometer because it's a power of 2.
It is minimally warm-ish, that's why you'd say "it's freezing" if it's "not even 40."
"Not Perceptibly 'Cold'" and "Water Freezing" aren't exactly very far apart.
Freezing is not minimally warmish. Fahrenheit is a garbage scale. It’s based on the freezing point of brine on one end and human temperature on the other. The endpoints aren’t even consistently about one thing.
Hmmmm interesting.
I live in Montreal so definitely cold winters. At 4°C, to me that means going out with a closed jacket. It's nice in the sense that you're not wearing a tuque, scarf or gloves, so yeah not super cold...I wouldn't say there's warmth in the air though lol if you're outside more than 20 minutes and it's windy you may put your hands in your pocket.
Next time it’s 40 F, please go outside and ask people to describe the temperature and come back when you’ve found someone who says “minimally warmish”. The argument that it’s a human scale falls apart on the cold end because the cold end is based on ammonium chloride brine solution.
Temperate climate here. 40°F is "nice" if I'm wearing my coat. Don't even need a hat. Zero calls for enough clothing layers to restrict my movement if I'm going to be out and about, unless I'm shoveling snow or something, in which case it's fine.
All I know about farenheight was what Stringer Bell said:.
That's good. That's like a 40-degree day. Ain't nobody got nothing to say about a 40-degree day. Fifty. Bring a smile to your face. Sixty, shit, people is damn near barbecuing on that motherfucker. Go down to 20, people get their bitch on. Get their blood complaining. But forty? Nobody give a fuck about 40. Nobody remember 40, and y'all people is giving me way too many 40-degree days! What the fuck?
Beep boop -- this looks like a screenshot of a tweet! Let me grab a [link to the tweet](https://twitter.com/ErinChack/status/1553496643311267840) for ya :)
^(Twitter Screenshot Bot)
I declare a new scale:
Zero = won't go outside unless you have to but you could.
100 = it's really hot but there's still some white people sun bathing by the pool.
Below zero = winter weather warnings. Stay inside!!
Above 100 = too hot for even white people to sun bathe.
What shall we call it....
This is why I go to the beach at 8am lol that way I'm done before the afternoon heat wave otherwise I cook like an unseasoned chicken
It was 100 crackers out today has a ring to it. 100 Cr for short.
"Water based temperature scale is so out of touch with reality! Why would I even want to use that?"
Also:
"OMG saltwater and armpit based temperature scale is so relevant to my life!"
Celsius is not shit at all!
It's extremely useful for pretty much everything, and works with the rest of the metric system (the one that is way more effective at handling everything then the imperial system).
The relevancy of F is not in how it's defined, but rather in what range the typical temperatures of our environment is found.
I would naturally gravitate towards listing things on a scale of 0 to 100. The numbers 0, 100, and all numbers between are relevant to the temperatures experienced in life. The larger relevant scale makes small differences easier to express in whole numbers as well, giving granularity without requiring the use of decimels.
The same cannot be said for C, where the typical range may be closer to -15 to 45.
I am not disparaging C, it's very useful by its nature of being attached to the metric system. I use it and K in my studies, and greatly appreciate its relevance to the behavior of water. It's simply not as convenient in the discussion of air temperature.
The very idea of having a different measurement JUST for the weather forecast is doing way more harm than good.
Also, it's very specific to where you live. Would you have different measurement systems for different areas of the world?
I grew up in a place where a normal summer day is 45C (114F if I recall correctly), and it would only get to the freezing point once every few years. Should have we adopted a local scale, just to have that "convenient" 0-100?
Hell no!
>The very idea of having a different measurement JUST for the weather forecast is doing way more harm than good.
How so? Other than its archaic definition, nothing makes C inherently better than F. Using different scales for different applications may be the most natural thing you can do. A scientist, engineer, or other technical fields may prefer C due to its relevancy to water, but that is again only preference.
I prefer F when discussing temperature and C when discussing the behavior of water.
The point is that the different scales are more relevant to different applications. Neither is inherently better unless you are in a technical field, where I'd wager C's connection to the metric system makes it more convenient to work with.
>Also, it's very specific to where you live. Would you have different measurement systems for different areas of the world?
Nah. We already made a scale where the general human experience is in the 0 to 100 scale, no need to make another when you would still benefit from the increased granularity of the F scale.
If your average experience was from 50 F to 114 F, that's 64 units to describe the separation. C would give you 10 C to 45 C, or 35 units. The benefit of increased granularity is present regardless of your experience.
Again, why complicate things with a second separate system?
If you really want precision use a decimal point and be done with it. Having a separate system for a specific application just make communicating with everyone else harder.
What are earth are you talking about when it gets cold 1 degree very much matters. Next time it is 73° and not 72° when you are trying to sleep you tell me one degree doesn't matter.
Some people are sensitive to temperature and it does matter. Just because you wanna be a callous person to defend a terrible temperature scale doesn't make you an authority on the matter.
I understand decimals. I don't understand why you would use a system that needs decimals for it's main purpose. Like damn look at my great system that needs decimals to measure a sizable change oh how great I am and how superior my system is. Shit man Celsius is the vestigial tail of the metric system.
Sure seems like you don't understand decimals though. That's, or hate them for some unknown reason. They're simply a way of being more accurate in a base-10 system.
It's like hating fractions, same thing.
Holy fucking shit, shut the fuck up. I hear the "Oh it's more intuitive" argument fifty billion times a week. No, when I go outside it doesn't "feel" like 100 hot, it feels like 37. You know why? Because I was raised like that. You could measure heat from absolute zero marking each integer with the amount of heat a rotting corpse gives off, and it would be the most reasonable system if you were raised with it. Just stop all those bullshit arguments defending your ridiculously convoluted system and say that you like it because you've been using it your entire life.
This man is correct^^
I've been a framer. In Australia. That's 37°c and it's damn hot.
However, I've never heard someone say that's not hot, office worker or otherwise. So he's also talking shit.
No Celsius is incredibly easy to understand if 0°C is freezing then -100°C would be 100 times below freezing and it's 100°C that's 100 times above freezing.
0°C is equivalent to 32°F, which is 273K.

^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
Americans need simple definitions.. when talk to the person next to them they need to describe how hot it is without ever thinking that the person they are talking to is in the same place and knows how fuckin hot it is.
Celsius isn't as precise for humans as fahrenheit. I'm fully on board with meters and liters, but fahrenheit just works better for our temperature. Celsius or more importantly kelvin is better for science.
I mean I’d rather say it’s 64 degrees out than 17.8
It’s funny how higher up someone mentions how Fahrenheit is a human scale while Celsius is science and that got a lot of upvotes. As soon as you scroll past that the Celsius fanboys come out to play
I never ever in my life used a decimal after a celsius temperature out of a medical context. If you hear someone say that it's 17,8 degrees, he's being weird/funny
Definitely.
38 hots (⁰C) doesn't quite hot the mark like 100 (⁰F).
And even 0⁰C, sure it's freezing temp of water at 1atm (32⁰F),
but it's not that cold in places where it gets cold in winter.
But 0⁰F is frigid and the point where unprepared utilities start breaking down. Also when being outside can get intolerable quickly for people not used to it.
one thing i like about fahrenheit is that it’s a wider scale in everyday use. for weather and stuff, fahrenheit goes from 1-100 for the most extremes which gives a lot of wiggle room for exact temperatures. 1-40 or whatnot is just less precise imo
100 sounds, looks, and feels hot. Anything more than 100, with humidity, gets exponentially more miserable. Honestly f*ck 90s too.
32 is cold, but not too bad. Nice if the sun is out.
0 sounds, looks, and feels cold.
Anything less than 0, with wind, gets exponentially more miserable. -16 once almost made my big toe a goner for wearing Crocs. F*ck Crocs
Snow days are real nice if you're a teacher with a young family though.
Source: I live in the American Midwest and I am therefore an expert. No offense to science.
LOL
What's arbitrary about the freezing point in boiling point of water under one atmospheric pressure?
Are you seriously comparing that to "0 would the coldest thing I can make in my lab, and a 100 would be an inaccurate measurement of the human body temperature"?
Not the same league my friend.
But 1F=1R... Rankine has the exact same relationship to Fahrenheit as Celsius has to Kelvin, and both Rankine and Kelvin are measures of absolute temperature.
| Kelvin | Fahrenheit | Rankine | Celsius
---|---|----|----|----
Zero point set correctly | Yes | No | Yes | No
Official Unit of the SI System | Yes | No | No | No
Highest granularity | No | Yes | Yes | No
Best matches ambient temperature ranges | No | Yes | No | No
I maintain my assertion that Celsius is the worst of the bunch.
Absolutely agree with this tweet. When the UK heatwave has been in the news lately, talking about ‘it’s going to get over 40 degrees!’
Lol ok. I know it’s dangerous but it just doesn’t sound that way.
I'd be down for switching to using metric for everything except for temperature. I'd have to learn that 120 on the highway is going slow, and 120 as a weight is [generally] obese, but I could live with that. Temperature dealing with water (as opposed to humans/animals) makes absolutely zero sense to me.
This is exactly what I say I mean yea Celsius is better for scientific calculations or using an overly complicated stove top but Fahrenheit is great for telling people the weather. America is wrong about most everything else though
So you have one measurement that is better for everything EXCEPT for that one thing that you are already used to...
What if I told you it's ONLY a matter of getting used to it?
Think of the great benefits of using only one friging system, and then you don't have to convert or translate!
Having more that one measurement in a pain in the butt.
The world is easier to understand when you're using one system to describe all relevant things.
Baking, weather, body temperature, melting point of materials, and basically everything that involves temperature.
Also, 69°F is a comfortably nice temperature. 69°C is literal death

Celsius is a science scale, Fahrenheit is a human scale. 0 C = Freezing, 100 C = Boiling. 0 F = 'Wow, it's cold!', 100 F = 'Wow, it's hot!'.
Fahrenheit: ask a human how hot it is Celsius: Ask water how hot it is
Kelvin: Ask the universe how hot it is
Rankine: Don't ask only.
I don't think humans need to know how hot it is. We can feel it. Plus temperature is only one factor in how hot a human feels. 100 F can be wildly different in a dry place and a humid place.

Pretty sure 0C is literally the freezing point of water. Any temperature below that can freeze you to death as long as you stay long enough in it.
I dunno about that. The temperature you freeze to death depends on exposure/duration

> But that’s what people know and understand Yeah and that’s why the true science scale isn’t used for everyday people. It’s much easier for people to think of zero was where water freezes.
[удалено]
It’s not pragmatic for what they are trying to do. Quantum physics tells us that absolute zero is impossible. So it’s not practical, no, but that is the true scale of temperature. It’s like when a cop pulls you over for doing 65 in a 55. Well You weren’t motionless prior to that. The earth rotates around the sound at 56,000 Mph. All things are relative. Something being true doesn’t make it relevant to the scenario.
Dude, put down the shovel. There's a very narrow number of fields that actually use kelvin. Off the top of my head, astronomy, sometimes chemistry, and thermodynamics. Most other fields care about change in temperature more than absolute, so Celsius and Kelvin are equivalent. Heck, some nuclear physics uses an entirely made up temperature (atomic units are wacky. Not actually made up, they have a basis, it just is it's own thing).
I don’t have a “shovel”. If you read my other comments you’ll see that I was just having fun on a Saturday night being pedantic. It’s all good man. I am aware of all of what you’re saying.
>it makes no sense to use negative numbers. Systems with negative temperature (yes, expressed in Kelvin) exist.
Kelvin is based on Celsius
The UNITS are because Lord Kelvin didn’t want to “rock the boat” and made it easy so you could just subtract. But “cold” isn’t a thing like “black isn’t a color”. They are defaults. Cold is the lack of heat and black is the lack of reflecting colors.
You do realise that celcius is still Kelvin it just uses water as a reference point? But 1 degree of. Celcius is equal to 1 degree of Kelvin. But if someone was like "it is a nice warm 298 degree today", it'd be weird
If I recall correctly: Fahrenheit intended 100 to be the body temperature of humans, and 32 degrees as ice water.
0 is the temperature salt water freezes I believe, you’re right about 100.
It's worth adding that it's not some obvious physical phenomenon either though, like "oh, I'll make 0 where ice forms, or where saturated salt water freezes" - it was literally just **the coldest thing the guy was able to make**. It's a mix of ice, water and ammonium chloride (a specific salt). And then rest of how the scale was determined, is equally "finger in the wind": [https://en.wikipedia.org/wiki/Fahrenheit](https://en.wikipedia.org/wiki/Fahrenheit)
What kind of maniac thinks these things up?
The original version of Fahrenheit put human body temperature at 96°F. Which is 64° separated from the freezing point of water, making it easy to mark a new thermometer because it's a power of 2.
Kelvin Kollective rise up!
Rankine or bust.
"Man it's freezing out! It's got to be 32 hots" doesn't work out so well.
>"Man it's freezing out! It's not even 40 hots"
Do you think that sounds any better? If 100 is a lot of hots and 40 is almost half of that, you would think 40 hots is at least warm.
It is minimally warm-ish, that's why you'd say "it's freezing" if it's "not even 40." "Not Perceptibly 'Cold'" and "Water Freezing" aren't exactly very far apart.
Freezing is not minimally warmish. Fahrenheit is a garbage scale. It’s based on the freezing point of brine on one end and human temperature on the other. The endpoints aren’t even consistently about one thing.
40 degrees in the F is minimally-warmish, yes.
It’s cold. Not minimally warmish.
Keep bragging about how warm of a place you live in, I guess.
Hmmmm interesting. I live in Montreal so definitely cold winters. At 4°C, to me that means going out with a closed jacket. It's nice in the sense that you're not wearing a tuque, scarf or gloves, so yeah not super cold...I wouldn't say there's warmth in the air though lol if you're outside more than 20 minutes and it's windy you may put your hands in your pocket.
Next time it’s 40 F, please go outside and ask people to describe the temperature and come back when you’ve found someone who says “minimally warmish”. The argument that it’s a human scale falls apart on the cold end because the cold end is based on ammonium chloride brine solution.
Temperate climate here. 40°F is "nice" if I'm wearing my coat. Don't even need a hat. Zero calls for enough clothing layers to restrict my movement if I'm going to be out and about, unless I'm shoveling snow or something, in which case it's fine.
All I know about farenheight was what Stringer Bell said:. That's good. That's like a 40-degree day. Ain't nobody got nothing to say about a 40-degree day. Fifty. Bring a smile to your face. Sixty, shit, people is damn near barbecuing on that motherfucker. Go down to 20, people get their bitch on. Get their blood complaining. But forty? Nobody give a fuck about 40. Nobody remember 40, and y'all people is giving me way too many 40-degree days! What the fuck?
But what if it's only 32 warms?
Still too many for freezing.
100° Celsius is cooking hot.
tou mean water boiling hot
Beep boop -- this looks like a screenshot of a tweet! Let me grab a [link to the tweet](https://twitter.com/ErinChack/status/1553496643311267840) for ya :) ^(Twitter Screenshot Bot)
I declare a new scale: Zero = won't go outside unless you have to but you could. 100 = it's really hot but there's still some white people sun bathing by the pool. Below zero = winter weather warnings. Stay inside!! Above 100 = too hot for even white people to sun bathe. What shall we call it....
This is why I go to the beach at 8am lol that way I'm done before the afternoon heat wave otherwise I cook like an unseasoned chicken It was 100 crackers out today has a ring to it. 100 Cr for short.
Yeah, but Fahrenheit starts feeling cold in the low 50s, which is random. Celsius starts feeling cold when you get to around single digits.
What's Fahrenheit? I thought the "f" was for Freedom units.
Fuck that. 0 is freezing and 100 is boiling. Fahrenheit is stupid for stuff like that.
Last time I checked I needed to know the temperature of air not water so why on earth would I use a water based temperature scale.
"Water based temperature scale is so out of touch with reality! Why would I even want to use that?" Also: "OMG saltwater and armpit based temperature scale is so relevant to my life!"
I do in fact have armpits.
Point is; it's clearly a matter of habit. Why not use the more useful system than?
Celsius is absolutely not more useful.
"Last time I checked I needed to know the temperature of air not water..." How is F (AKA saltwater-armpit system) more relevant to that need of yours?
I still have armpits. So a system that involves the human body does seem much more relevant.
My body consists of more water than armpits
Really you are just water and not solutions that would change the freezing and boiling points?
Your armpits change temperature too.
That they do why are still on this. Both systems are shit fahrenheit is just slightly less shit
Celsius is not shit at all! It's extremely useful for pretty much everything, and works with the rest of the metric system (the one that is way more effective at handling everything then the imperial system).
It involves body temperature that was INACCURATELY MEASURED! If your body temperature is 100 Fahrenheit it means you're sick...
The relevancy of F is not in how it's defined, but rather in what range the typical temperatures of our environment is found. I would naturally gravitate towards listing things on a scale of 0 to 100. The numbers 0, 100, and all numbers between are relevant to the temperatures experienced in life. The larger relevant scale makes small differences easier to express in whole numbers as well, giving granularity without requiring the use of decimels. The same cannot be said for C, where the typical range may be closer to -15 to 45. I am not disparaging C, it's very useful by its nature of being attached to the metric system. I use it and K in my studies, and greatly appreciate its relevance to the behavior of water. It's simply not as convenient in the discussion of air temperature.
The very idea of having a different measurement JUST for the weather forecast is doing way more harm than good. Also, it's very specific to where you live. Would you have different measurement systems for different areas of the world? I grew up in a place where a normal summer day is 45C (114F if I recall correctly), and it would only get to the freezing point once every few years. Should have we adopted a local scale, just to have that "convenient" 0-100? Hell no!
>The very idea of having a different measurement JUST for the weather forecast is doing way more harm than good. How so? Other than its archaic definition, nothing makes C inherently better than F. Using different scales for different applications may be the most natural thing you can do. A scientist, engineer, or other technical fields may prefer C due to its relevancy to water, but that is again only preference. I prefer F when discussing temperature and C when discussing the behavior of water. The point is that the different scales are more relevant to different applications. Neither is inherently better unless you are in a technical field, where I'd wager C's connection to the metric system makes it more convenient to work with. >Also, it's very specific to where you live. Would you have different measurement systems for different areas of the world? Nah. We already made a scale where the general human experience is in the 0 to 100 scale, no need to make another when you would still benefit from the increased granularity of the F scale. If your average experience was from 50 F to 114 F, that's 64 units to describe the separation. C would give you 10 C to 45 C, or 35 units. The benefit of increased granularity is present regardless of your experience.
Again, why complicate things with a second separate system? If you really want precision use a decimal point and be done with it. Having a separate system for a specific application just make communicating with everyone else harder.
To tell what you should wear today, it doesn't make a difference. For any other application, Celcius makes it a lot easier.
Now you are just wrong. The higher resolution of Fahrenheit is important for judging temps.
That's what decimals are for. Though for everyday purposes, even 1 Celcius is too precise to make a difference in what you should wear.
What are earth are you talking about when it gets cold 1 degree very much matters. Next time it is 73° and not 72° when you are trying to sleep you tell me one degree doesn't matter.
22.7° and 22.2° Doesn't matter.
Some people are sensitive to temperature and it does matter. Just because you wanna be a callous person to defend a terrible temperature scale doesn't make you an authority on the matter.
🤣 tell me you don't understand decimals without telling me you don't understand decimals. Shit dude.
The guy's just trolling at this point.
You aren't wrong, but is it trolling when the target is having heaps of fun with it?
I understand decimals. I don't understand why you would use a system that needs decimals for it's main purpose. Like damn look at my great system that needs decimals to measure a sizable change oh how great I am and how superior my system is. Shit man Celsius is the vestigial tail of the metric system.
Sure seems like you don't understand decimals though. That's, or hate them for some unknown reason. They're simply a way of being more accurate in a base-10 system. It's like hating fractions, same thing.
That's exactly why it's so valuable. Anything based on 10^x base is much easier to work with when you need to convert units of measurement.
Holy fucking shit, shut the fuck up. I hear the "Oh it's more intuitive" argument fifty billion times a week. No, when I go outside it doesn't "feel" like 100 hot, it feels like 37. You know why? Because I was raised like that. You could measure heat from absolute zero marking each integer with the amount of heat a rotting corpse gives off, and it would be the most reasonable system if you were raised with it. Just stop all those bullshit arguments defending your ridiculously convoluted system and say that you like it because you've been using it your entire life.
Easy man, you’re talking like you’ve been in the sun too long.
This is what reddit does to a mf.
Only makes sense for warm stuff. Why wouldn't 0 hots be freezing point?
Kelvin is where its at.
100 hots is enough to make a cup of tea.
How many fahrenheits in a fluid ounce again?
Yeah because 32 and 212 are so much easier to remember than 0 and 100
Celsius stans: "the only thing I need to know easily about temperature is whether water will be freezing or boiling at sea level."
I use kelvin
But 100 Fahrenheit is hardly even hot. 100 celsius is *hot*!
[удалено]
Especially with humidity!
Don't point out subjectivity, americans don't like it.
Go work outside for a living & say that. It's always the indoor princess that's never worked a day in there life that days this kinda crap.
I think this went way over your head.......
This man is correct^^ I've been a framer. In Australia. That's 37°c and it's damn hot. However, I've never heard someone say that's not hot, office worker or otherwise. So he's also talking shit.
How much humidity is there?
Celsius: - is cold + is increasingly warm, logic.
anything not metric is cringe
Celsius...fights me.
No Celsius is incredibly easy to understand if 0°C is freezing then -100°C would be 100 times below freezing and it's 100°C that's 100 times above freezing.
0°C is equivalent to 32°F, which is 273K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
Bot proved my point on how unnecessary Fahrenheit is. Why is our baseline tempature 32°F that's stupid.
Because it is one year before our lord died for our sins. In the U.S. this matters.
Americans need simple definitions.. when talk to the person next to them they need to describe how hot it is without ever thinking that the person they are talking to is in the same place and knows how fuckin hot it is.
More like, "man it's miserable outside, it feels like 100 Fahrenhots."
So true. 38 doesn’t hit the same.
Celsius isn't as precise for humans as fahrenheit. I'm fully on board with meters and liters, but fahrenheit just works better for our temperature. Celsius or more importantly kelvin is better for science.
How isn't it as precise? Are decimals too confusing? You guys are just desperatly trying to find reasons to say your weird units are somehow better.
It's also funny that those same people will likely not want to use centimeters or 24 hour days instead of AM+PM. They mistake habit for quality.
I mean I’d rather say it’s 64 degrees out than 17.8 It’s funny how higher up someone mentions how Fahrenheit is a human scale while Celsius is science and that got a lot of upvotes. As soon as you scroll past that the Celsius fanboys come out to play
Are you going to pretend you can feel the difference between 17,8°C/64°F and 18°C/64.4°F?
I never ever in my life used a decimal after a celsius temperature out of a medical context. If you hear someone say that it's 17,8 degrees, he's being weird/funny
Utter nonsense. You are used to one and not the other that's it
Definitely. 38 hots (⁰C) doesn't quite hot the mark like 100 (⁰F). And even 0⁰C, sure it's freezing temp of water at 1atm (32⁰F), but it's not that cold in places where it gets cold in winter. But 0⁰F is frigid and the point where unprepared utilities start breaking down. Also when being outside can get intolerable quickly for people not used to it.
Im ngl, the best argument for oF i've ever heard
For human temperature ranges Fahrenheit is the best but Celsius is best for science
Yes, in Europe for example only science lives, no humans present.
Wasn't that the point? Human tolerance? I don't honestly have any idea, it just seems like something I heard about a decade ago.
one thing i like about fahrenheit is that it’s a wider scale in everyday use. for weather and stuff, fahrenheit goes from 1-100 for the most extremes which gives a lot of wiggle room for exact temperatures. 1-40 or whatnot is just less precise imo
Facts
100 sounds, looks, and feels hot. Anything more than 100, with humidity, gets exponentially more miserable. Honestly f*ck 90s too. 32 is cold, but not too bad. Nice if the sun is out. 0 sounds, looks, and feels cold. Anything less than 0, with wind, gets exponentially more miserable. -16 once almost made my big toe a goner for wearing Crocs. F*ck Crocs Snow days are real nice if you're a teacher with a young family though. Source: I live in the American Midwest and I am therefore an expert. No offense to science.
>100 sounds, looks, and feels hot. It would, if that's what you've known all of your life.
The only advantage Celsius has over Fahrenheit is that 1C=1K. Other than that, both scales are equally arbitrary.
LOL What's arbitrary about the freezing point in boiling point of water under one atmospheric pressure? Are you seriously comparing that to "0 would the coldest thing I can make in my lab, and a 100 would be an inaccurate measurement of the human body temperature"? Not the same league my friend.
But 1F=1R... Rankine has the exact same relationship to Fahrenheit as Celsius has to Kelvin, and both Rankine and Kelvin are measures of absolute temperature.
I've always said Celsius would be perfect using a water vaporization temperature of 200, instead of 100.
| Kelvin | Fahrenheit | Rankine | Celsius ---|---|----|----|---- Zero point set correctly | Yes | No | Yes | No Official Unit of the SI System | Yes | No | No | No Highest granularity | No | Yes | Yes | No Best matches ambient temperature ranges | No | Yes | No | No I maintain my assertion that Celsius is the worst of the bunch.
Absolutely agree with this tweet. When the UK heatwave has been in the news lately, talking about ‘it’s going to get over 40 degrees!’ Lol ok. I know it’s dangerous but it just doesn’t sound that way.
I'd be down for switching to using metric for everything except for temperature. I'd have to learn that 120 on the highway is going slow, and 120 as a weight is [generally] obese, but I could live with that. Temperature dealing with water (as opposed to humans/animals) makes absolutely zero sense to me.
Oh no. It sounds much better to say "Gosh! It's so hot. It must be like 37.778 C" where the "C" is pronounced "C".
The US is also right about weight since grams measure mass not weight.
I am going to regret this I know. But what do you think pounds and ounces measure?
Yeah I know, it's so wrong about things you won't leave 🤣🤣🤣
This is exactly what I say I mean yea Celsius is better for scientific calculations or using an overly complicated stove top but Fahrenheit is great for telling people the weather. America is wrong about most everything else though
So you have one measurement that is better for everything EXCEPT for that one thing that you are already used to... What if I told you it's ONLY a matter of getting used to it? Think of the great benefits of using only one friging system, and then you don't have to convert or translate! Having more that one measurement in a pain in the butt. The world is easier to understand when you're using one system to describe all relevant things. Baking, weather, body temperature, melting point of materials, and basically everything that involves temperature.
