During the French Revolution, they tried to make a right angle have 100 degrees and even recomputed all new trig tables for this new standard. It obviously did not catch on :)

There's no reason you can't have 400 degrees in a circle and therefore 100 for a right angle.

It's a degree scale: you can choose any number you want.

Indeed, gradiens are a scale where a circle is divided into 400 equal parts. Really fucked me up a few times when I got a new calculator and wasn’t paying attention to what the little “grad” meant.

But I can't subdivide 400 in to as many ways as 360. Think about the pie industry. They could be put out of business!!

Of course that's true, that doesn't mean you should.

The Indiana pi bill mandated certain mathematical values be changed to the wrong value.

“The bill, written by a physician and an amateur mathematician, never became law.”

Some pocket calculators from not too long ago supported this unit for some reason, along with radians and degrees. That's the third option on "DRG" button.

Whenever I'm late to a meeting I blame it on the french revolutionary calendar.
