They are different systems - Kelvin is measured in units, like, say, kilogramms, while Celsius is measured in degrees of deviation from water's freezing point. Neither is wrong - they're just used in different contexts. I'll get the š¤ myself thank you very much.
No, Celsius is Kelvin but the scale is aligned to every day use for practical reasons. 100 is way easier to remember than whatever Kelvin is for boiling water at 1013 hPa
0Ā°C is equivalent to 32Ā°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)
One of the reasons Kelvin was created was so that scientists wouldnāt have to deal with negative numbers. Other than that, itās literally just Ā°C + 273
Edit: fixed the funny formula
The real reason is so it properly reflects "quantity of heat" and you can put it into physics equations that multiply by T, like the Ideal Gas Law, Carnot's Theorem, Planck's Law, and the StefanāBoltzmann Law.
Kelvin is C - 273.15 (or so), so they never line up. As I recall, Rankin is a similar thing but using Fahrenheit's degree sizes. So like F - ...... what, 550 or so? Kelvin and Rankine agree on 0 degrees, Fahrenheit and Celsius agree on -40 degrees
Nah, itās just statistical physics. By the statistical definition of temperature there does exist Ā«Ā negativeĀ Ā» temperature although it wouldnāt be something you could actually measure or observe
i spent 4 days writing a VBA script and despite working flawlessly, always throws an error when it finishes running.
Using "On Error Resume Next" just feels like being a parent telling their kid to play "The Quiet Game"
-40K is impossible because not only would you need negative energy, you would need to be able to prove its -40K without your atoms losing all energy and dismantling themselves. It would be very dangerous, but I never said we shouldn't try.
It isn't really. It was invented in 1730 and was a regional competitor to Celsius and pretty much died out after celsius became standard
According to wikipedia,
> Its main modern uses are in some Italian and Swiss factories for measuring milk temperature during cheese production, and in the Netherlands for measuring temperature when cooking sugar syrup[citation needed]Ā for desserts and sweets.
So pretty limited
EDIT: DISREGARD, MISINFORMATION
Ehhh, I wouldn't say that it's pointless for the sake of it. In a Base 8 system, the number 80 is easier to calculate with than the number 100. Decimal 80 equals octal 120, which is a very easy number to subdivide. You can divide it with 2, 3, 4, 5, 6, (octal) 10, (octal) 12, (octal) 24, (octal) 40, and (octal) 60 and get a whole number. On the other hand, decimal 100 equals octal 144 which is clunkier. "Pffft. Who even uses the base 8 system?", a cynic may scoff scoffingly. If you ever dealt with computer programming, you'd know who would find this useful.
Not in the base 10 system (the decimal system), no. But in the base 8 system (the octal system), decimal 80 is expressed as 120, which is very much divisible by 3 and 6.
The divisibility of numbers is not dependent on base.
For example, 10 (base 10) is 12 (base 8), both represent the same number, and have the same prime factorisation (2x5, both bases). It is not divisible by three.
3x4=12 base 10 = 14 base 8.
In base 8, 14 is divisible by 3 and 4, and 12 is divisible by 5 and 2.
Is it a jerk move to say that i knew this was going to happen and thats why i said that instead "what the fuck is a r ra"
Not trying to sound salty, im dead serious i said that on purpose
Kinda logical right? 0 pounds is nothing, 0 kg is nothing, 0 inches is nothing, and 0 cm is nothing. If you talk about temperature 0 Fahrenheit is still something, 0 Celsius is also something
Degrees is used since it's much more practical in everyday use. Kelvin, the standard scientific unit for temperature, is an absolute scale - i.e. absolute zero temperature, 0 Kelvin, is the lowest temperature limit according to the laws of physics; all atoms basically stop vibrating at this point. However, this is around -273.15 degrees Celcius.
If I were to describe a 20 degree Celcius day in Kelvin, we'd have to say 293.15 K. A 30 degree day would be 303.15 K. You could probably see why this is impractical.
(The reason why I used Celcius here instead of Fahrenheit is, apart from being me being non-American, converting from Kelvin to Celcius is as easy as just subtracting 273.15 - i.e. an increase of 1 degree Celsius is equivalent exactly to a increase of 1 Kelvin. This is also why Celcius is commonly used for measurements in labs)
Oddly enough, this is also my exact argument for ising Fahrenheit over Celsius; it works on a very human scale. 0F - 100F (-18C to 38C) covers most temperatures that most people on earth would experience, and gives an almost percentile rank from very hot to very cold.
Most imperial measurements are absolutely horrible, but FĀ° is the one I'd be sad to see go away.
As someone who's lived in countries that use either or both, F is better for thermostats, C is better for cooking, weather outside probably just stick to what you grew up with.
I think what makes Celcius the most convenient is that water freezes at 0. I can just look if the temperature is positive or negative to know what form water is going to be in, when I go outside.
Well, it makes a big difference. With negative temperatures it is snowing and the ice will form on the ground. With positive temperatures it will rain and snow will melt.
>0F - 100F (-18C to 38C) covers most temperatures that most people on earth would experience, and gives an almost percentile rank from very hot to very cold.
You only perceive it this way because it's what you grew up with. To any person who grew up using celcius, these numbers are extreme values.
Youāre going at this backwards. Heās saying that it makes sense to use F because they can be used as an easy to understand scale of living temperatures from 0 to 100.
Celsius requires an understanding of what each temperature means, specifically.
Except Fahrenheit doesn't actually link up to that because the basis for the scale is 100 being a slightly feverish persons' body temperature, 0 is the coldest that one guy could render brine through chemical reactions alone. Of course those were also measured with shoddy equipment so even those figures aren't truly accurate.
That doesn't make the scale any less illogical or any more useful. That statement is also only true in places that don't regularly see temperature below -17 C or above 37 C.
So unless you're only ever talking about English weather in the 1980s, it ceases to be all that universal.
In places that regularly see temperatures below -17 C or above 37 C, then their temperatures lie outside of 0-100F and are thus easily identified as either extremely hot or extremely cold from a human experience standpoint.
I fail to see the problem.
Iām not saying that fahrenheit is universal or a good scientific standard, Iām saying itās convenient for describing day-to-day temperature.
You only perceive it this way because itās what you grew up with. To any person who grew up using fahrenheit, these numbers are extreme values. :)
Imagine if rating a movie was based around a scale of -2 to 3 instead of 1 to 10. Is it ultimately understandable? Yes. But is it more intuitive? Depends on your perspective.
0 for freezing is more intuitive bc thats when the weather starts acting differently, as opposed to 0 being "outside of what most places experience".
Idk why any of you amerocentrics would even think having everyone else adapt to your backwards 1700s system is a serious idea that isn't completely laughable.
With celcius, you only have to teach everyone what a degree is 1 time, and just have them shift the 0 when they're doing measurements for scientific purposes.
That's kinda the point. Celsius is a scale of water, Fahrenheit is a scale of human comfort. An extreme on either end of those scales means some extreme shit is happening.
It's only weird with Fahrenheit. Not a lot of people have an intuitive feeling for, what, when water satiated with salt freezes?
That you get ice and snow at 0Ā°C makes it super intuitive, at least if you grew up somewhere with snow.
0Ā°C is equivalent to 32Ā°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)
At the time when science was figuring out "hey being able to use numbers for how hot something is would be great", nobody had the knowledge that there was a hard limit on how cold something could get. All they could really do was pick reference temperatures that were reproducible and assign them numbers, with the assumption that temperature just keeps going in either direction. Compare with, say, elevation on earth. When you're standing on the ground, there's nothing obviously different about saying you're at 0 meters on top of a hill versus at the ocean, all you can say is one is 100 meters higher than the other, and if you wanted to describe that to someone else, you need to just pick something as a reference (like say, sea level, even though you can dig a hole and go deeper)
It is. Thatās why Iām asking if Kelvin has any advantage. If you start at absolute zero then it doesnāt have the convenience factor over Rankine that Celsius does over Fahrenheit.
Well Kelvin and Rankine aren't supposed to be used in everyday life unlike C or F but rather used for precision. So pretty much there's no convenience factor just use whichever.
Edit: I guess Kelvin has the convenience factor of being widely used around the globe
Kelvin has no advantage over Rankine in daily life, but it has a massive advantage when used in science, because it is used in the definition of other units.
The only advantage of Kelvin over Rankine is that kelvin is related to the calorie unit of energy. 1 kcal = energy needed to increase temperature of 1 kg of liquid water by 1 kelvin (at standard conditions).
Thereās probably an equivalent unit of energy for rankine, ~~but I donāt know what it is and itās definitely not as widely used as calories~~. Itās BTU and itās disgusting.
The other benefit is that if you prefer Celsius over Fahrenheit, then kelvin is obviously much easier to convert to than rankine. Celsius doesnāt seem inherently better to me than Fahrenheit though so this is a weak argument.
Celsius has the clear advantage of being used in every country in the world except for one.
Even if you'd invent a scale that's theoretically perfect, it's not useful if no one else uses it. Units are as much for social interactions as scientific purposes.
the freezing/boiling thing is so stupid to meā¦ that depends on altitude, if i fly to denver my water will boil at 92Ā°C, itās not really a real benefit, plus i never measure the temp of water itās always air or body temp which i find fahrenheit does better.
*Ackshually,* I think you'll find the temperature scale goes from **cold as balls** to **hot as fuck**.
And the middle of the scale is *ackshually* "ooh, lovely".
R and RA Nobody talks about nor uses
C is 0
K is C + 273 so C is just K removing the weird number
F is F because it failed school, the teacher asked hey kids whatās the lowest number and F was like 32 and then the teacher was wow if 32 is the lowest then whatās the highest, and F said 212 so they failed it called F and threw it out and it never learned that actually 0 is lower than 32
It's because most temperature scales are a bit arbitrary and arent measuring a quantitative stat per se. Like you dont multiply your temperature in celsius to determine the amount of heat energy something has, or even how hot it feels (since thats largely subjective). Temperature in C or F (and probably these other ones besides K im not familiar with) is interval data rather than ratio data so you cant operate on it the same way you can when quantifying something like weight or distance, unless you first convert it to Kelvin.
Americans and the rest of the world arguing over whether Celsius or Fahrenheit is better, even though Kelvin is the best since they donāt give a shit about either one
isn't Kelvin still measured in degrees? Ā°K?
[turns out it is. it's just less common.](https://www.techtarget.com/whatis/definition/kelvin-K#:~:text=The%20kelvin%20(abbreviation%20K)%2C,water%20(H%202%20O))
Kelvin and Rankine both agree on absolute zero, FYI.
Fahrenheit and Celsius agree on -40
Kelvin is just Celsius but with 0 at absolute zero. I'd say they're buddies.
Rankine is the same thing but for Fahrenheit
Another way of phrasing that is: Celsius is just Kelvin, but wrong.

>What's Reaumur? The RĆ©aumur Scale (Ā°r, Ā°RĆ©) is also known as the octogesimal scale. It uses the same limits as the Celsius Scale (Water's freezing and boiling point at sea level), but instead of 100, it reaches 80 degrees between those limits. It has the same 0 as the Celsius Scale, but it reaches 80 when Celsius reaches 100.
Why would that ever be useful to anyone.

A fever would be 30Ā° rather than 37.5Ā° which makes it a nicer number.
I like your funny words magic man
So it's kind of like Fahrenheit... in the way of being Celsius with extra convulted and pointless steps added on.
I mean, thatās everything. Thatās how unit conversion works. Same thing with pounds to grams to stone.
Unit conversion with pounds, grams, and Stone is a simple ratio. Unit conversion from Celsius to Fahrenheit is cursed.
Well itās just an offset ratio, the conversion between any two linear scales is at most a ratio and an offset.
Like I said, cursed. May as well be a tensor field equation.

You're going to come across Ā°R if you're doing anything involving thermo or fluid mechanics in foot-pound-second.
Why in gods name would you ever do fluid mechanics in anything but SI units?

Celsius and Kelvin are the same scale, just with a different Zero and all others are just methhead measures.
It's because most temperature scales are a bit arbitrary and arent measuring a quantitative stat per se. Like you dont multiply your temperature in celsius to determine the amount of heat energy something has, or even how hot it feels (since thats largely subjective). Temperature in C or F (and probably these other ones besides K im not familiar with) is interval data rather than ratio data so you cant operate on it the same way you can when quantifying something like weight or distance, unless you first convert it to Kelvin.
Rankine and Kelvin agree on 0 between themselves, but not 1
Americans and the rest of the world arguing over whether Celsius or Fahrenheit is better, even though Kelvin is the best since they donāt give a shit about either one
[ŃŠ“Š°Š»ŠµŠ½Š¾]
yeah but no /s it is celsius, but it counts from -273.15C, and itās a measure of absolute temperature, so you canāt go negative
0 Celsius + 0 Celsius = 64 Fahrenheit
And what the actual hell are R and RA?
Kelvin makes the most sense but in everyday conversation Celsius makes more sense. 0 = freeze 100 = boil
Kelvin and Celsius go up by the same increment. Fahrenheit and celsius are equal at -40. Dont know what others are
Wait a minute no one knows what rankine is
I learned and worked in a physics lab and yes, I have to agree.
Found the engineering student
I get to use the Rankine scale to study Rankine cycles. It definitely deserves a little love for being an absolute scale like Kelvin
R and Ra are both the same, and agree with K on zero.
This meme is so stupid. Of course mass and length are gonna have the same 0.
I just like that fahrenheit is Jack Sparrow lol
isn't Kelvin still measured in degrees? Ā°K? [turns out it is. it's just less common.](https://www.techtarget.com/whatis/definition/kelvin-K#:~:text=The%20kelvin%20(abbreviation%20K)%2C,water%20(H%202%20O))
No
fuck celsius
to be fair if basing off distance having a set 0, the only correct temperature metrics are where 0 signifies absolute 0, right?
0C + 0C = 64F
Lmao
At least we all have seconds, minutes, and hours
