I bet a lot more people know what 0°C feels like than 0°F. One is freezing point, one is a completely arbitrary temperature which only gets called “the lowest you’ll experience” as a post hoc rationalisation of Fahrenheit. Most people will never experience anything that cold, some people experience colder.

I even bet more people know what 100°C feels like than 100°F. One is accidentally getting scalded by boiling water, the other is a completely arbitrary temperature which is quite hot but not even the hottest you’ll experience in America.
