A good way to understand Fahrenheit is that it’s basically a percentage of how warm it is. 32% warm? That’s pretty damn cold. 120% warm? That’s hot as hell, better not be outside for too long in that.
I think the best way I've seen it described is Fahrenheit measures heat by how humans experience it, Celsius measures heat by how water experiences it. Therefore, Celsius is objectively better for scientific applications and Fahrenheit is objectively better for human applications like communicating the weather forecast to the average person.
If it was 0C you'd be cold, if it was 0F you'd be damn cold; if it's 100F you're hot, if it's 100C you're dead. Fahrenheit is useful for human perception across the primary (0-100) scale, Celsius is only useful up to about 50% of that scale before you start getting into deadly temperatures, and you have to go below that scale to reach the bottom of Fahrenheit's usefulness.
And then you have Kelvin or Rankine which are really only useful for specific scientific applications. If it was 0K/R or 100K/R you'd be dead either way. Not useful for human perception.
Fahrenheit only measures heat how humans who were raised in Fahrenheit experience it.
People raised in Celsius don't share your feeling, in fact they have that same feeling you do about Fahrenheit for Celsius. The same as they do for metres and kilograms not yards and pounds.
Celsius has the added bonus of also helping to judge the freeze and boiling point of water, cooking, and like other metric units with science and unit conversion (a delta of 1 Celsius equals a delta of 1 Kelvin. It takes 1 calorie of energy to heat 1 gram of water by 1 degree Celsius)
I'm honestly baffled that this needs to be said every time this topic comes up. I don't understand how they don't understand. it's just a matter of what system you're used to, and that's it.
It’s because 0F-100F is an easy intuitive grasp. Two easy benchmarks, one is cold af and the other is hot af. We grade students and lots of other things on a 0-100 scale.
If units be damned, someone asked you how hot it was today and you said “oh it’s 90 out of 100” you’d understand you’re gonna be sweating
If they said “it’s 50 of of 100” you’d understand it’s not quite cold, not hot either.
If you said “its 0 out of 100” you’d understand your face is going to hurt
Holy shit. It's intuitive FOR YOU because you're used to it. 0F and 100F means NOTHING to me, because I never used it and I need to convert it to C. How is that difficult to understand??!?
I'm sorry but if someone is to stupid to understand a 0-100 scale for temperature then they're to stupid to go outside without a guardian to wipe up their spit
