Sorry but that makes no sense to me.

Is 0% hot no extra heat, like perfect room temp or is it zero heat, the death of all life?

What does 100% hot mean?

You arranged it for yourself to make sense of it, but no need to rationalise it. It’s only good, cause you’re used to it, or doesn’t “feel more human” than Celsius.

I’ve been in a sauna with 100°C ( what’s that? 250°F?) It’s doable, but that’s probably my personal max. So 100°C air temp is now 100%? Mmmh doesn’t really work that great.

All in all, temperature unit is just data points, the interpretation is individual. Fahrenheit is not “more suitable for humans” than any other unit.
