The SI unit scales are chosen to fit together to avoid “respectable” scientific calculations.
To heat one milliliter (1 ml) of water one degree Celsius (1 °C) you need one calorie (1 cal) of energy.
Also the dimensions of one milliliter, is one cubic centimeter (1 cm^3), and that amount of water weighs 1 gram (1 g).
Thus 1 liter of water needs 1 kcal of energy to heat up 1 °C.

Celsius is literally just Kelvin but shifted… So it’s just as friendly for “universal math”.

K is just shifted °C though and just removes what’s nice about it with freezing/boiling of watee while requiring 3 digit numbers for every temperature you’d encounter in daily life. I think I’d rather use Fahrenheit

It wouldn’t even change the difficulty, really. You’d just wind up multiplying or dividing by 9/10 instead of 9/5.

America moving zero to Celcius’ zero would be better, it would remove one whole step from the calculation
Then if they made their degrees about 9 fifths the size (they could get higher resolution than they’d lose by doing what we do and quoting temperature to one decimal place where needed) it would be dead simple to convert (just change the symbol from °F to °C!)
