# Degree to all other angle unit conversions

## Degree

Degree is a measurement of plane angle where one full rotation is considered as 360°. It is not an SI unit, as the SI unit for angles is radian.
As one full rotation= 2π where one degree= π/180 radians
A division of a circle, equal to 1/360 of its circumference.

### History:

No specific origin for the usage or who first subdivided the circle into 360 degrees. History doesn't record who first decided to subdivide a circle into 360 degrees and how this number was chosen. It seems likely that it was chosen due to its closeness to the number of days in a year, and because it has an unusually large number of numbers by which it can be divided. Timocharis of Alexandria is credited as one of the first Greeks to use 360 degrees and he lived between 320 and 260 BC. Before that, the Rigveda mentions a wheel divided into 360 pegs. The Rigveda was written between 1500 and 1200 BC.
