Americans when faced with a Celsius measurement in the EU: "Oh, 32°C, that's about 90 degrees."

EU people when faced with Fahrenheit in an arricle about a place in the US: "Reeeeee, why isn't this in my own comfortable units that I like‽‽"

Look, guys, we need an entire generation to finally die before we can fix a lot of things here in the US. We've got larger problems than imperial or metric units right now. We're working on it, amd your petulant whining about units makes you look silly to a country of people who are used to converting between the two.

If you are discussing the affects of temperature on humans, you should use a human centric temperature scale, so I'd say that is already the appropriate unit.
