At least personally I think the 0 to 100 scale with the average global temperature being somewhere in the mid 50s I think makes sense. Sure there's some people in warmer places and some on colder places that will say 0 and 100 farenheit aren't that bad but for people in a more temperate environment it works as a good scale. But yeah I do agree at the end of the day it is whatever you grew up with and it doesn't really matter that much. It's just that for temperature there isn't as concrete of a reason to switch to metric compared to lengths and weights.
