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.
IMO it makes more sense if the humans in Star Trek are unreliable narrators.
How is it possible that a teenage mechanic can improve engine efficiency by 5% messing around in his spare time? Why didn’t the engineers whose full time job it is to build the engines figure that out?
In fact, cosmic radiation in space drives all humans insane. They truly believe they’re doing science experiments, but stuff goes wrong because they’re just jamming random household items into the engine.
