I’m happy with metric generally speaking - except for Celsius when talking about ambient temperature. I will die on that hill. Freezing/boiling point of water is a ridiculous point of reference for temperature as experienced by humans.
Fahrenheit: 0 = really cold; 100 = really hot
Celsius: -17.778 = really cold; 38.333 = really hot
Not to mention that the Celsius grading is too big requiring use of tenths when discussing weather and setting a thermostat…
It’s really hot for a human way before 100°F, it’s becoming uncomfortable when it’s more than 77°F (or 25°C for most humans. The “100 really hot” part is not really a benefit for anyone.
Also the point when water freezes is pretty important in the winter. You can see immediately that you have to drive carefully when the temperature is close to 0°C. So I think 0° freezing makes the most sense.
However: Temperature of boiling water is useless, that’s true.
Because of that the scale of Fahrenheit was different above the Freezing point of water and below, requiring to redefine the temperature at the reference points multiple times (and not by an insignificant amount)

Fahrenheit automatically disqualifies itself from being a serious unit, because it has an inconsistent scale
This reply really confuses me - in what way is the scale inconsistent?
The original definition is using three points:
