Nah, it doesn’t make any sense, and isn’t deep or insightful at all.
Let me explain. Anything below 0F is really cold for a human, and anything above 100F is really hot. The Fahrenheit scale was built around human biology.
0C isn’t even that cold, and 100C is literally instant death. Thus, Celsius is less applicable to the human experience and more applicable to the physical properties of water. The typical range of human scale temperatures is like -10 to 40 degrees on the Celsius scale? Makes no sense.
Kelvin is the most scientifically objective scale, but also the least intuitive for humans, because absolute zero is completely outside our frame of reference.
So it’s easily demonstrable that Fahrenheit is how people feel, Celsius is how water feels, and Kelvin is how molecules feel.
Be forewarned that I am willing to die on this hill, and any challenges to my position will result in increasingly large walls of text until you have conceded the point 😤
main arguments from below
Celsius is adequate because it’s based on water, and all life on earth is also based on water, so it’s not totally out of our wheelhouse. But for humans specifically I think Fahrenheit is the clear answer.
One point that many may overlook is that most of us here are relatively smart and educated. There are a good number of people on this planet who just aren’t very good with numbers. Obviously a genius could easily adapt their mind to Kelvin or whatever.
You have to use negative numbers more frequently with Celsius > Celsius has a less intuitive frame of reference
Each Celsius degree is nearly two Fahrenheit degrees > Celsius is less granular
The reason I argue the more granular Fahrenheit is more intuitive is because a one degree change should intuitively be quite minor. But since you only have like 40 or 50 degrees to describe the entire gamut of human experiences with Celsius, it blends together a bit too much. I know that people will say to use decimals, but its the same flaw as negative numbers. It’s simply unintuitive and cumbersome.
B) 66F is room temperature. Halfway between freezing (32F) and 100F.
the intuition is learned and not natural.
All scales have to be learned, obviously. It’s far easier to create intuitive anchorpoints in a 0-100 system than a -18 to 38 system. Thus, Fahrenheit is more intuitive for the average person.
I should note that if you are a scientist, the argument completely changes. If you are doing experiments and making calcualtions across a much wider range of temperatures, Celsius and Kelvin are much more intuitive. But we are talking about the average human experience, and for that situation, I maintain Fahrenheit supremacy
Final edit: Well, I got what I asked for. I think I ended up making some pretty irrefutable points with these two last ones though. Once again, math saves the day. If somebody wants to continue the discussion make another thread and tag me because this is a bit much for science memes.
further arguments
It’s not about the specific numbers, but the range that they cover. It’s about the relation of the scale to our lived experience. Hypothetically, if you wanted to design a temperature scale around our species, you would assign the range of 0-100 to the range that would be the most frequently utilized, because those are the shortest numbers. It’s not an absolute range, but the middle of a bell curve which covers 95% of practical scenarios that people encounter. It doesn’t make any sense to start that range at some arbitrary value like 1000 or -18.
When the temperature starts to go above the human body temperature, most humans cannot survive in those environments. Thus, they would have little reason to describe such a temperature. Celsius wastes many double digit numbers between 40-100 that are rarely used. Instead, it forces you to use more negative numbers.
This winter, many days were in the 10s and 20s where I live. Using Celsius would have been marginally more inconvenient in those scenarios, which happen every winter. This is yet another benefit of Fahrenheit, it has a set of base 10 divisions that can be easily communicated, allowing for a convenient level of uncertainty when describing a temperature.
the end is nigh
Generally -40 to 40 are the extremes of livable areas.
Sure, water is a really good system and it works well.
And for F that range is -40 to 104. See how you get 64 extra degrees of precision and nearly all of them are double digit numbers? No downside.
Furthermore F can use its base 10 system to describe useful ranges of temperature such as the 20s, 60s, etc. So you have 144 degrees instead of just 80, and you also have the option to utilize a more broad 16 degree scale that’s also built in.
You might say that Celsius technically also has an 8 degree scale(10s, 30s), but I would argue that the range of 10 degrees Celsius is too broad to be useful in the same way. In order to scale such that 0C is water freezing and 100C boiling, it was necessary for the units to become larger and thus the 10C shorthand is much less descriptive than the 10F shorthand, at least for most human purposes.
The Fahrenheit scale was built around human biology.
Nope, it was built around the highest and lowest extremes some dude could create in his room. Not based on human biology in the slightest. Don’t repeat this false information.
0C isn’t even that cold, and 100C is literally instant death.
Yeah, but counter argument, who gives a shit? The “meme” doesn’t say anything remotely close to “from 0 to 100”. I don’t know why you are under the impression that these scales become inaccurate if you leave the 0-100 range. I live in a region that frequents -40C to +40C over a year- that’s centered on zero, so it’s already better for “how humans feel” than being centered on 32 and pretending there is some cosmic/celestial/god ordained reason for it.
Kelvin is the most scientifically objective scale, but also the least intuitive for humans…
Still no one giving a shit- the “meme” doesn’t remotely even suggest anything related to this.
Be forewarned that I am willing to die on this hill
I don’t know why you sign this off with “I’m an obnoxious twat”, but I’m perfectly happy with using the block function if the threat is real.
A) Fahrenheit has an appropriate level of granularity for humans
B) Fahrenheit has an intuitive frame of reference for humans
Celsius and Kelvin do not.
I don’t want to fight about this I just think it’s actually true, and I also think Europeans get insanely defensive about stuff like this for no reason.
I like watching people dying in this hill, more power to you. I don’t necessarily agree, but telling people it’s negative anything just to say it’s pretty cold is indeed less intuitive to me (and kids don’t even know negatives until a bit older).
Only thing is, 100 doesn’t need to be anyone’s scale, with C I think of it more like a scale from 10 to 40, especially since I live in California, and F is more a scale from 50 to 110. It’d probably help if F really was based on human temps, with 100 being the average temp whenever you measure, instead of 96 to 98.
(An aside, neither are ratio scales. 0 in both cases are arbitrary and a temp of 100 isn’t twice as hot as 50. Only Kelvin is like that, which makes it my favorite even if it’s never intuitive, haha)

Huh, TIL. That’s actually pretty cool. Kelvin moving up the rankings 😅
Did it never occur to you that Celsius is basically Kelvin with the zero point moved to human reference?
Human reference because >50% of our body is water. We are essentially water bags.
When I was a kid, I learned about negative numbers pretty early on. It was a perfectly normal part of life, since the temp was in the negative a lot of the year. Made sense to me. Temp is below zero? Water is solid. . Temp above zero? Water is liquid. Fahrenheit doesn’t make much sense to me, inherently, because I don’t have an integral frame of reference, built over decades of familiarity. Celcius on the other hand, it just makes sense!
Only Kelvin is like that
False. Rankine is too.
I didn’t find any others in a quick glance at the wiki, but it would be easy to imagine a scale like 0 at absolute zero, and 100 at the freezing point of water or something.
The typical range of human scale temperatures is like -10 to 40 degrees on the Celsius scale? Makes no sense.
But it makes so much sense though. Because it’s anchored around the freezing and boiling points of water, which is a universal experience we can all relate to. 0°C outside? It’s freezing.
Fahrenheit as “the human scale” is what makes no fucking sense. You end up with the same exact problem where your specific range of “human scale temperatures” does not line up with 0-100°F at all. But it’s also not anchored to water’s behavior. So it just ends up being arbitrary.
But it makes so much sense though. Because it’s anchored around the freezing and boiling points of water, which is a universal experience we can all relate to. 0°C outside? It’s freezing.
It does make sense. But no, I cannot personally relate to being H2O and freezing into a block of ice or evaporating into the air.
As a human, I can relate to when I feel cold, and when I feel hot. And a scale where I feel hot at 30 degrees and cold at -10 is not even remotely intuitive.
You end up with the same exact problem where your specific range of “human scale temperatures” does not line up with 0-100°F at all.
Human scale temperatures do line up with 0-100 on the Fahrenheit scale. Certainly much better than 0-100 on the Celsius scale. How are you even disputing that???
Whenever I think that I have seen it all in one of these °F vs °C threads, someone comes along and proves me wrong.
No, the F scale was not built around human biology, that is pure conjecture from people who can’t let go of their antiquated system of measures.
But you go die on that hill, I won’t stop you.
Thoughts?

-10C or 10C: Pretty comfortable
-20C or 20C: Starting to feel bit cold or hot
-30C or 30C: Uncomfortably cold or hot
-40C or 40C: Almost painfully cold or hot
How exactly is -40F to 104F better than that for human purposes?
Anything below 0F is really cold for a human
Anything below 10F is really cold for a human too, and so is anything below -10F what’s your point?
100C is literally instant death.
While commonly between 80 and 100, finnish sauna temperatures up to 110°c are not unheard of.
Very hot, but definitely not even close to instant death.

Really? My whole thesis paper about how humans immediately explode into a million pieces when they reach 100 degrees Celsius is completely ruined. How will I ever recover?

My point is self evident, you’re willfully ignoring it.

Looks like you made the mistake of posting this when the European downvote gang was awake.
I just got absolutely obliterated. Believe it or not, I got up to +10 on that initial comment at one point. I think if I had formally presented my argument initially, it may have gone better.
I just didn’t realize that mentioning Celsius was going to set off this kind of reaction. It’s so weird the things that different cultures hold sacred.
My argument is actually pretty simple, but people could always challenge these assertions, in which case it would get more complicated.
A) Fahrenheit has an appropriate level of granularity for humans

Celsius and Kelvin do not. Celsius is adequate because it’s based on water, and all life on earth is also based on water, so it’s not totally out of our wheelhouse. But for humans specifically I think Fahrenheit is the clear answer.
One point that many may overlook is that most of us here are relatively smart and educated. There are a good number of people on this planet who just aren’t very good with numbers. Obviously a genius could easily adapt their mind to Kelvin or whatever.
But Fahrenheit is the temperature scale of the proletariat, the working man, the average Joe. And I’m here for it.
You mean other than the fact only a tiny proportion of people in the world use Fahrenheit?
It didn’t say which people. Also, I’m from South East Asia and have used Fahrenheit my entire life as a means to measure body temperature using mercury thermometers during fever time. It’s so much easier to say whether a fever is above 100 or not and then how much above 100.
So people do feel in Fahrenheit. A fuck ton of them do.
Yes, I know the meme is about the weather but… take a chill pill and look at your prejudices.
Celcius is how I “feel”, because that’s the scale I’ve learned and can relate to.
Farenheit is what you “feel” for the same reason.
It’s not because one is intrinsically better linked to our bodies.
You’re missing the point. The scale is what matters, not your personal experience or unit preference. From 0-100 F is right about what a human could be expected to tolerate without much help. In C, that’s -18-38. That’s a much more limited range in terms of human tolerance, but it works great for water, which would be 0-100 C. The scale doesn’t translate as well to K, but it does end at 0, so there’s that.
“Fahrenheit is how people feel” only makes sense if said people have never used another scale. You know how 100F “feels” because that’s what you use. If you used Celsius you’d know how that scale feels instead, and be used to using the more useful scale generally.
See also: people who think they don’t have an accent.
You know what? I just enjoy being able to set a thermostat to a comfortable level by just using whole numbers instead of resorting do decimal places.
100 f is pretty close to average body temperature.
So above 100 means your surroundings are hotter than your body is unless you have a fever.
I think that’s an okay land mark.
Notice how the tweet doesn’t say “all people”. Context is everywhere and everything.
It only works if you grew up in a country that uses Fahrenheit. I didn’t, so to me Celsius is how I feel. I’ve no idea whether 20 f is jeans and a t-shirt weather, or if I should be getting my coat. 20 c however I know that as long as it’s not windy I’ll be good with jeans and a t-shirt, but that it’s still a little too cool to get out my shorts.
Americans always regurgite the “Fahrenheit is how people feel” nonsense, but it is just that: nonsense. Americans are familiar with fahrenheit so they think that it is more inituitive than other systems, but unsurprisingly people who are used to celsius have no problems using it to measure “how people feel” and will think it is a very inituitive system.
It is really easy to map onto human feel though. 0-100 pretty accurately maps onto our minimum and maximum realistically survivable temps, long-term, and the middle temperatures of those are the most comfortable. It’s far more round, when it comes to describing human preference and survivability, than Celsius is.
I bet a lot more people know what 0°C feels like than 0°F. One is freezing point, one is a completely arbitrary temperature which only gets called “the lowest you’ll experience” as a post hoc rationalisation of Fahrenheit. Most people will never experience anything that cold, some people experience colder.
I even bet more people know what 100°C feels like than 100°F. One is accidentally getting scalded by boiling water, the other is a completely arbitrary temperature which is quite hot but not even the hottest you’ll experience in America.
boiling water isnt necessarily 100c. if youre boiling water, it can be any arbitrary temperature above 100.
thats like going to a geyser pit and saying thats 100c, when it isnt. when you cook and let water come to a boil, the chef doesnt care that its exactly 100c, only that its in the state above 100.
What? People experience 100 f regularly. It’s literally their body temperature.
No it doesn’t, unfortunately.
What makes 0F (-18C) special? How do you estimate survivability at such temperature? If I’d be out on the street naked, I would die there in a matter of minutes. At the same time, there is plenty of places where winter temperatures go -40F (-40C) and even below, yet people very much survive and live there.
Similar with 100F (38C). There are places with higher temps in the summer, up to 120F (49C) in some places, yet people survive. Still, if you’re not equipped with anything, 100F (38C) will burn you alive.
All that not to mention that 50F (10C) is actually cold, not comfortable.
Fahrenheit is only intuitive and “feeling-descriptive” because you’re used to it. From a person born in Celsius country, it’s really not less intuitive. I know I can be comfortable in my birthday suit at around 25C. Less than 20 is chilly, less than 10 - cold, less than 0 - freezing. More than 30 is hot, more than 40 is deadly.
0F is the temperature a freezer needs to be to keep food fresh.
50F is the point that you can’t survive without clothes, your body will not generate enough heat.
100F (38C) will not burn you alive. You can survive for a long time in a sauna at 200F.
100F is perfect hot tub temperature
I wanna say that with this logic 50 should be right around the most comfortable temp… But for most people it’s closer to 70.
I’ll try to explain how easily mappable Celsius is to people as well.
-40 to +40… -40 being extremely cold, and +40 being extremely hot. 21c is the equivalent of 70f.
It’s all the same stuff. Just matters what you’re used to.
0-150 is the better range, and 75 is right in the middle. 100 is just a hot air temperature most people don’t want to be in but it’s not an extreme.
Saunas can get up to 200 degrees
Hot tubs are usually at 100
Freezers need to be at least 0
You say 15°C. 6° cooler than room temperature. But how much is 6°?
It’s 60°F.
50°F or 10°C is where you need clothes to survive
300, 325, 350 is where you bake cookies (149-176°C)
Fahrenheit has a bunch of 5 and 10s
Saying something like high 70s or low 70s for temp represents an easy way to tell temperature.
21° to 26° for celcius
I walk outside and say “It feels like high 70s today” someone using celcius would say, “Feels like 25°”. If it was a little warmer than “low 80s” compared to “Ehh about 26 or 27°C”
Both are equally arbitrary. You just have to know a handful of temperatures that you use in your day to day life either way.
Celsius being based on water makes it the most intuitive of the three imo.
Hum… Around here water boils at ~96°C (some labs measure that). And it seems to not freeze at 0°C anywhere on Earth, as it’s never pure water, with never an homogeneous freezing point.
It is repeatable, it’s not very arbitrary, but “intuitive” doesn’t apply in any way.
Can confirm. Moved from the US to Canada and maybe a year of using Celcius revealed to me just how fucking stupid and convoluted Fahrenheit is. My dad spent three weeks out here and started using Celcius on his phone. Now I only use Fahrenheit when dealing with fevers or temping cases of suspiciously overripe produce.
Fellow Americans. Celcius is superior and more intuitive for those who take a moment to adjust to it. It is okay to accept this as fact without developing an inferiority complex. USA not always #1. USA quite often not #1 and that is okay. It is okay for USA to not be #1 without developing an inferiority complex.
Fahrenheit has a fine granularity that is lost in cold climates. It’s why the Bahamas/Belize use it as well.
Well you know that you can use the decimals?
How is - 40.000001°F more fine than - 40.00000000001°C?
23°C is a nice room temperature.
18°C is a bit chilly but still a comfortable temperature.
If you want to go for a finer destinction then we cann say 18.5°C is warmer but I personally can’t feel the difference.
I like that Fahrenheit has a narrower range for degrees. 1C is 1.8 degrees F. So, F allows you to have more precision without the use of decimals. Like, 71F feels noticeably different to me than 64F, but that is only a 3.8 degree difference in C.
But that also doesn’t matter because the granularity is meaningless if you don’t make decisions for differences between 71F and 70F
Not at those exact temperatures, but one degree matters in in grilling meat, making mash for beer, making candy, etc.
I mean, you’re 100% wrong. Fahrenheit isn’t “how people feel” arbitrarily, it’s almost literally a 0-100 scale of how hot it is outside. You need no prior knowledge to interpret a Fahrenheit measurement. Which really reflects poorly on everyone who says “Fahrenheit doesn’t make any sense” because if they were capable of any thought at all they would figure it out in 2 seconds, like everyone else. I’m a lab rat that uses Celsius all day every day, I’m just not a pretentious stuck up tool about alternate measurements just because I refuse to understand them.
“Human scale”. Snort. What bollocks.
Tell me that you are American without telling me you are American
Ok.
“Hey. Come over and get some BBQ and food that doesn’t look like sad beans. We can talk about how boring a soccer game is when one team leads and they just play keep away for 40 minutes. Man, this corn on the cob is so good. Sure glad my teeth are straight so I can eat it super easy. Anyone else enjoy having a complete global dominance on movies, tv, and pop culture? How about the internet?”
Careful not to burn yourself at that BBQ 'cos you’ll have to go into debt to afford a sticking plaster. That is if any gathering of Americans larger than two doesn’t just immediately devolve into a mass shooting again. Maybe you’ll see a weather balloon and have to hide indoors from the Chinese.

The nation’s “national passtime” is baseball lmao I don’t think we have a leg to stand on there bud.

Also you seem to be saying this as though it’s a good thing…
Most people are inherently biased towards their chosen system. A “water scale” doesn’t make sense to fahrenheit users, and a “human scale” is dismissed as even existing by the Celsius users. But hey, if you want to fight, have at it. It’s annoying and pointless, but that’s what the internet is for.
Did it never occur to you that Celsius is basically Kelvin with the zero point moved to human reference?
Human reference because >50% of our body is water. We are essentially water bags.
This is interesting but not really justified historically. Celsius predates the concept of absolute zero, and water is very important to our world, not just ourselves.
how do you calibrate a fahrenheit thermometer? With celsius it’s hilariously trivial, if the thermometer says it’s about 0 when you see water freeze, it’s correct enough for everyday use.

You do the exact same but use 32 degrees instead of zero. I know celsius is cool and good but most people seem incapable of understanding how its just fucking marks on a line and any non-sciencey advantage is pretty much null.
“human scale” is dismissed as even existing by the Celsius users
Celsius user here.
I find “I’m more used to it, therefore it makes more intuitive sense to me” is a perfectly understandable argument.
The problem with the human scale argument is that it makes it sound completely arbitrary.
To a human there is no objective difference between -1F, 0F or +1F. They are all about the same degree of “cold”.
Is there a difference between 19, 20, and 21 Celsius? It’s also pretty subtle. Yes, there’s a bigger difference than fahrenheit, but I’ve never cared regardless of scale down to what degree the temperature is. As a fahrenheit user, it’s always 10s. 0-10, 10-20, etc.
Is there a difference between 19, 20, and 21 Celsius?
First off, nobody claimed that Celsius is based on human perception so humans not being able to differentiate between these is simply irrelevant to the argument.
Second, the bounds of 0 and 100 are based on the freezing temp of water which are specific, non-arbitrary temperatures.
I’m not arguing one system over the other, I just think the “human scale” argument has been made up just to have an argument.
Is there a difference between 19, 20, and 21 Celsius?
Yes, as anyone that’s ever worked in an office can tell you.
Edit: Apparently I was expecting too much cognitive ability / common knowledge so let me be clearer: Generally women prefer it warmer (>20), men like it cooler (<20). It’s a very common office discussion.
i mean a lot of measurements are arbitrary necause their manmade. thats creation of measurements in a nutshell. they exist to give people context to conpare to. time is a manmade construct, unit of length is a manmade construct. unit of weight is a manmade construct.
for instance with 1 kilo, tell me the last time a regular person had platinum-iridium ingot. its completely arbitrary.
tell me the last time a regular person had platinum-iridium ingot
What, you don’t?
But yeah, I agree, units are made up. I mean, why is the boiling point at 100C and not any other number? Someone made it up.
I’m just saying the argument “0F is really cold” is just as true as -10F is really cold or +10F is really cold.
I’m honestly just so tired. Could I snap my fingers and have the US switch to metric units with everyone understanding them as intuitively as the units they grew up with, I would. I really don’t have an emotional attachment to what letter appears next to the temperature.
We couldn’t even stick the the unanimously popular bill to abolish DST. This issue is so much further down the list of priorities and yet so much more expensive to change that I don’t expect it to come up during my lifetime. To spend the next few decades arguing about it without any hope of a meaningful resolution sounds like my personal hell.
