Metric: 1 calorie heats 1 gram of water 1 C°, 1 gram is equal to 1cm³. Water boils at 100 C° and freezes at zero.
Imperial: 1 calorie heats 1 something by ?? F equal to ???, and 0F and 100F are completely irrelevant to everyday life and tasks.
I get your point, but disagree with your thesis. Fahrenheit makes a lot of sense for human comfort ranges. 0 and 100 are some of the most extreme natural temperatures most people in F-using countries ever see. 0 means cold as fuck and 100 means hot as fuck. And there’s a single-digit useful precision to it as well. 72 and 73 are close, but noticeably different. Celsius requires decimals for that kind of difference. And 0 means “it’s kinda cold outside, I guess” and 100 means “you were dead a long time ago”, so it’s not nearly as useful in every day life with natural living temperatures.
If it requires this much explanation, it's not very sensible.
In Celsius 0 is freezing and 100 is boiling. It's so simple. "Comfortable" is anywhere from like 15-30 (my Canadian standards, very subjective I know) and we don't need decimals.
But it's not that simple. 100 boiling is only true at sea level. At 530 (~1750 feet) it's 98c. At 1500m (~5000ft) it's down to 95c. At 3000m (10k feet) it's just under 90c. Ocean water freezes at -2c. Fully saturated salt water freezes at -21c.
Fahrenheit doesn't have this issue?
Fahrenheit and Celsius both have the exact same issues. Which is why there isn't much reason to switch.
Temperatures can be given more accurately in Fahrenheit with whole numbers
