Obviously both can be adapted to. But if you took a group of aliens and asked them to come up with a temperature scale that was only used to convey how cold or warm the temperature felt to humans, they would almost certainly use human body temperature in their design process not the freezing and boiling points of water.

This isn’t to say that Celsius isn’t perfectly fine and superior in most ways. I’m not insulting anyone or attempting to participate in some kind of culture war.

Celsius is obviously a better scale for determining when water freezes. But I’ve never found myself paying attention to that. Mostly because any problems that I’d worry about related to the water freezing happen well below freezing.

But if you find yourself unable to agree that one system has some inherent advantages over another, even if they don’t outweigh the disadvantages, you should step back and think a little more objectively.
