Celsius tried to fit too much into 100 notches to please big math.

F is more nuanced with more notches, but the ends aren't logical. It coukd be shifted perhaps, but how?

If freezing was moved to 0, then water boiling would be 180

Perhaps C could have had a 200 degree range, then it would be closer to F and not so hard to convert.

But also: Scientists are important and we shouldn't make it too easy, it demeans their work. Maybe make the C scale show water boiling at 183.4521 degrees so scientific calculations are more impressive-looking and respectable.

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.

I'm aware, taught that in school.

Also aware of the real world, those things don't mesh the same at altitude.

In theory, reality and theory are the same. In reality, they're not.

I love science when it's not treated like a religion.
