It's just designed with a slightly different set of assumptions.
Instead of water freezing and boiling 100° apart, it's 180° in fahrenheit. That makes it so that they're on the opposite sides of a temperature gauge, and a degree of rotation of the gauge matches a degree of temperature.
Instead of zero being the freezing point of water under specific conditions, it's a brine solution whose temperature will stabilize in a way that's useful for using as a calibration point.
Stripped of its context, it's odd. But it's not irrational, just no longer consensus as the standard, and as such deprecated.
Fahrenheit makes sense for humans. Most of your day to day climates are in the 0 to 100 scale, and every 10 degrees is a noticeable level change.
100 super hot day, approaching unsafe without counter measures
90 really hot day, slightly annoying and should take precautions
80, hot day, more annoying than anything
70, beautiful day, enjoy it
60 not to bad, if it's windy you could be slightly on the cold side
50 long sleeves or maybe a hoodie
40 definitely a jacket, and hat
30 full on coat, scarfe, and hat
20 multiple layers of out for a while, maybe double pants
10 annoyingly cold, need to start thinking about the safety precautions
0 and below, temperature now measured in hold long you can be outside before danger
Celsius makes sense for science stuff because it's derived from science stuff, so things like calories and energy work with it. But it doesn't really apply to everyday life as well. So it actually makes sense to use both units for the things the are good at.
It depends on what you were raised with. For me I have all these relevant points in my head for C. 25 is nice, under 20 you slowly need to dress longer stuff. Over 30 is hot, over 40 sucks hard, over 50 can become deadly soon. Body temp is around 37.
I don't science anymore, but living in a F country, I keep in mind for conversions:
0C is freezing point of water ~32F
20-22C is room temp ~68-72F
30C+ is Unhappy temperatures/hot.
Really only things I need to remember, and gradient based off of. It can get up to 45C where I live, but that would never be important to me. I hate the heat, if it's 30C+, the degree to which it is hot matters little, I'm going to just want to stay out of the sun or go inside.
Here 70F is perfect weather. For reference we set our a/c at 68 at night and it's literally freezing cold if you walk though in your underwear. Any hotter and you'll need to start dressing in lighter stuff. Any colder and you might wanna wear a flannel. Hell my house stays at 72 all day and it's perfect.
Being from outside of the US I'm used to Celsius for everything, so I can make the same list, the numbers are just not whole 10s and I would probably round to nearest 5.
Just an fyi, 100F is not “unsafe without counter measures” level of hot. That would be around 115+F. I say this as someone from a city that regularly hits 120F during the summer. 100 you can still get in your car, 115+ you need to wear gloves or else you’ll get 3rd degree burns. 100 have to buy pizza for lunch, 115+ just bake a pizza in your car.
I work outside in the Texas sun. 100F is unsurvivable without regular water intake and regular breaks. That would literally define it as unsafe without counter measures. You're talking about walking to your car. We're talking about actually being in it. Like playing a sport or fishing. 110 here means you can only work in short 15-20 minute bursts. 100 and you're sweating so profusely your entire shirt Is soaked. At 90 it's warm and a little toasty. At 80 it feels pretty good out. At 70 is literally the perfect temperature. 60 starts to get a bit on the chill side. 50 is light jacket weather. 40 is heavier jacket weather. 30 is a winter coat and multiple layers. Works just fine for us. If you don't like it then don't use it. I don't even know why this argument is so prevalent. It's not complicated like y'all would like everyone to believe.
Yeah, I was using getting into your car as an example because our burn center has to put out a warning every year due to people literally burning their hand off getting into their car. Like I said, my state regularly gets to 120 in the summer. Texas rarely gets that hot. I’ve already stated in my previous comment that you’d need to drink more water, but it’s not going to fucking kill you. Hell, during summer we are lucky if it gets below 105 at night. You’re being really dramatic with the whole “my shirt is soaked in sweat!!” When you obviously live in a humid area. It being 70 in Florida will get you the same results. Like seriously, 100 ain’t shit, yeah drink more water, but you don’t need to stop every 2 minutes for a water break. 110 here means construction crews stop working at 2 instead of 6, and no there are no 10-15 increments of working. You shouldn’t only be drinking water, which will make you sick, anyways. You should also have an intake of oral salts to balance everything out. And it will prolong your need for water. And for the record, I was homeless for years so I have literally lived in the heat and seen countless people die from exposure. No one ever died when it was 100 out.
Never. They use the same spacing between degrees. The Kelvin scale was derived from the Celsius scale, just placing the 0° at absolute zero rather than at the freezing point of water.
Fun fact time, -40F is -40C.
And 575F is 575K
Fahrenheit is a strange scale.

A F country? You can just say the US, I doubt it'd be Cayman Islands or Liberia lol.

They probably don't understand numbers not ending in 0.

That's why they added the word "approaching"
It's funny to assume that all people using Celsius are unable to ascertain how they will feel outside based on the temperature value.
I mean, I understand that round numbers are cute, but we are able to handle numbers ending in 5 as well as numbers ending in 0.
Somebody's from the north. Even as warm blooded as I am 80 is a nice day and 90 is just annoyingly hot.
And at what temperatures are C and K equal?
Never. They use the same spacing between degrees. The Kelvin scale was derived from the Celsius scale, just placing the 0° at absolute zero rather than at the freezing point of water.
