I've always found the use of kWh/year so absurd. I mean Wh is kinda weird as a unit for energy, but this is just plain asburd.
1 Wh = 3600 joules
Degrees are ridiculous if you're doing calculus. They don't really pose any problems if you're doing trig.
> but working with irrational fractions of pi is ridiculous if you're trying to measure with a protractor.
Sure, that's true, but that's only because irrational numbers are by definition infinitely precise. It's no more difficult to use a protractor labeled in increments of 0.02 radians than one labeled in increments of one degree.
0.02 radians would absolutely be a ridiculous unit of measurement if you were a carpenter or draftsman in the age before computing.
But if you're trying to measure an angle, this is totally irrelevant. The angle is whatever it is.
Are you trying to measure an angle, draw a particular angle, or confirm that an angle meets a particular standard?
My real surprise and problem comes with Wh/x, where x is any unit of time. Why not cancel h/x for any dimensionless factor? This is what the grandparent is referring to.
