I mean, it's arbitrary. I've lived in a Fahrenheit country and a Celsius country and both systems work fine. Resolution issues exist for both systems (you can still benefit from decimals in Fahrenheit for coffee and tea brewing)

I prefer Fahrenheit because it's based around the human, but it really doesn't matter, and it's probably better long term to have measurements that are not based around the human condition, but we're talking about benefits to society tens of thousands of years from now, rather than today.
