I do concede the overwhelming majority of people that argue that one is better than the other (both ways) are basically just arguing "the thing I grew up with is better" - because when you probe further, there isn't really any supporting argument, just "I understand this system better because I grew up with it" but it's equally vacuous coming from people who grew up with Celsius.

I came to the US when I was 12, so I grew up with Celsius but didn't pay attention to the weather as a young child. But still, I've lived in both systems.
