Where did the 360 degree for a circle convention come from? By any chance, is it from the ~360 days for the earth to revolve around the sun?
Yes. That's how we get 60 sec. = 1 min. and 60 min. = 1 hr. for time, and also 60 sec. = 1 min. and 60 min = 1 deg. for angle.they worked in base 60 didn't they?
