The only temperature scale that isn’t arbitrary is Kelvin, because it has an actual absolute zero. So 0 in Farenheit is freezing point of water and salt solution, which does have scientific application. What difference does it make? The compression of the Celsius scale forces you to use decimal points for any kind of reasonable daily use which sucks. I am not saying Fahrenheit is better, I am saying neither is better. They are both arbitrary. It doesn’t matter which one you prefer, it’s just what you are used to. The other metric units are objectively superior and given to greater precision.
