In Celcius water boils at exactly 100°C, and you don’t have to round, and 50°C is exactly half the boiling point of water.

unless you’re doing literal chemistry, the specific boiling point of the water doesn’t matter, especially for any subjective referential experiences you might have, such as, going outside.

(You’re just fucking with us right? Like Celsius is has a coarser base unit, and the range applicable to human temperatures are not such pretty numbers, but you can’t be seriously thinking Fahrenheit makes more sense for when we talk about water?)

i’m not saying it’s better, i’m just saying you’re having a failure of imagination to conceptualize the usage of the fahrenheit system if you so pleased to use it in such a specific manner, which almost nobody here does. You could still do it though.
