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.
- 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.
  
  Fahrenheit is European.
- 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
  
  3 degrees celcius is easily noticeable too so that's a bit of a moot point. If anything, 1 degree celcius is much harder to discern and therefore having an even more granular scale is unnecessary.
- 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.
- 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.
- 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 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.
  
  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.
  
  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.

Tell me that you are American without telling me you are American
- Now, now you get your People pass cancelled.
- 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?"
  
  You’d never hear any Americans talking about soccer unless their kids were playing in a Rec league
  
  Found the American

Kelvin is for scientists.
Celsius is for people.
Fahrenheit is a translation layer between Celsius and Americans. All their weather stations have been Celsius for ages, it's a societal decision to use an arbitrary unit instead. The "69F censoring" which turned out to be a rounding artefact illustrated that nicely. Their government could change that, power to them that they decide not to 🤷‍♂️
- fahrenheit is literally defined by celsius at this point, afaik celsius is literally the official standard of the united states but everyone just.. keeps using fahrenheit anyways
  
  There's also no such thing as an inch. It's defined by the meter, there isn't an official yardstick.
  The only reason the UK, Canada and USA used the same inch is because they needed to interchange parts for weapons and machines during WW1. Despite all thinking they used the same measurement system the definition had drifted between them. Metric was defined by enlightenment people with better methods of reproducing the standard. So it was easier to adopt a inch definition based on 25.4mm.
  The UK and US inch only match because of WW1. The imperial volumes are still different.

Honestly? I’ve only lived in countries with Celsius and Celsius is how I feel. I know exactly how hot or cold a day is gonna be if I look up the temperature. Thats how I know what clothes to wear!!! But Fahrenheit confuses the shit out of me. Every time I visit the US, I always convert the temp back to Celsius when someone tells me the temp.
I know Fahrenheit has more degrees and that can give you more datapoints. But cmon. The temp only goes up to, like, 50 C anyways lol. How many degrees do you need 🤣. Can you really differentiate between 61 and 62 F? Now, 60 to 65 F might be believable, but that’s like 15 to 18 C so, that much difference is shown even in Celsius.
I’m not saying Celsius is better, or that Americans should convert to it. Actually, if I was God-Emperor, I’d force us all to use Kelvin,, given it begins with Absolute Zero and I’m a sucker for shit like that.
But variety is the spice of life. For Americans, Fahrenheit is how they feel. For most of the rest of us, it’s Celsius.

"Human scale". Snort. What bollocks.

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 😤
  
  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.
- Try having fun every once in a while
- What’s the flaw??
  
  "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.

Celsius can be used in place of all three, the others cannot.
The freezing point of water is also a great place to zero the scale.
- i love this idea that water is completely irrelevant to humans, as if it's not like 60% of our mass and vital to living
  yeah no let's base the temperature scale around what some english dude felt was comfortable
- Plus 100 is boiling it's a perfect scale.

Fahrenheit isn't how people feel, it's how brine solutions feel.
- Which is a surprisingly good approximation for how people feel. 0-100 is pretty survivable, with the mid ranges being most comfortable, and things outside of that range starting to pose serious threats.
  
  50F (or 40-60F) is not the most comfortable for...well, anyone i think. Thats pretty chilly for most people, with 60F being the low side of comfortable (both inside and outside). Most universally comfortable temperature range is probably around 70-80F, which is not really "around the middle" in that 0-100 range. 70F is ideal inside temperature, 80F is a nice warm summer day outside.
  
  0-100 is pretty survivable
  I can tell you've never been outside when it was 0°F

At this point, there’s no harm in using Fahrenheit. We can convert it to celcius. But please use a sane date format.
- ISO 8601

I don't get it...people freeze at 0F and boil at 100F?
- No, but those describe pretty well the range within people tend to do okay in. Anything lower or higher and you tend to need more specialized gear and have to seriously limit exposure.
  
  You need specialized gear at less than 0F and more than 100F? So totally fine to wear t-shirt and shorts anywhere in between? Just face facts...F is a completely nonsensical system with no basis in any reality.

Reading these comments, my spiteful genie wish is to invent and proliferate a log base 10 scale, something like earthquake magnitudes or decibels. Y'all hate F or C? Welcome T, where 1 equals 1 Kelvin, 2 equals 10 Kelvin, 3 equals 100 Kelvin, 4 equals 1000 Kelvin, and so on.
It's easy! Humans live somewhere around 3, as does boiling and freezing, while the sun is between a 4 and a 5 at the surface and the core is closer to an 8.
- Take a look at the mean molecular kinetic energy.
  As a bonus, it's measured in Joules. Or eV if you want a sensible unity, but I don't think you'll want it.

But it doesn't really make sense, it's just some nonsense that sounds clever
