I like the saying “Fahrenheit is what you feel, Celsius is what water feels, and Kelvin is what the universe feels”.
Fahrenheit is what Americans feel, Celsius is what everyone else feels, and Kelvin is just Celsius +273.
Fahrenheit is what everyone feels. It’s a scale of 0 to 100 of how hot it is outside. Excluding extreme outliers, it covers the range of temperatures the average human might experience. In Celsius that’s like -20 to 40. I personally use Celsius anyway, because I don’t consider it much of an inconvenience, but Fahrenheit is certainly the more human-centric scale.
This is no way describes how I feel. I almost never experience below -5C, e.g. like 20F, but from there down it doesn’t really matter if it’s 10F or -10F. You need special clothing and then you’re fine.
While my pain point is at 95F, most people I know consider “hot outside” being around 80F, and “unbearably hot outside” at around 88F. So, how is this intuitive?
Fahrenheit is what that one German town’s lowest air temperature measured back in 1708.
If fahrenheit was what humans felt, then 50° would be room temperature.
