I'm gonna be honest. I love Celsius for the the whole perfect math reasons with calories and water based measurement...
But the curve on temps is a pain when all the nice temperatures require using a decimal place to decide just how slightly above or below pleasant it is but cold is basically everything from 16°C to -30°C And then decimals really matter when hotter than pleasant temps.
Whole rounded integers are just so vastly different depending how high or low you are in Celsius.
