Plane angles have been measured in many different units. The most contemporary units are the degree ( ° ) and radian (rad), but many others have been used throughout history.
The radian (rad) is the SI unit for measuring angles. one radian is just under 57.3 degrees. Accepted prefixes still not accepted in pure math.
A degree (others names: the degree of arc, arc degree, or arcdegree), the degree symbol (°), is a measurement of a plane angle, the degree is as that a full rotation is 360 degrees.
Divide the degree value by 57.295778
radian = degree / 57.295778
Multiply the radian value by 57.295778
degree = radian x 57.295778
One radian (rad) is equal to 57.295778 degree (°)
1 radian (rad) = 57.295778 degree (°)
One degree (°) is equal to 0.017453 radian (rad)
1 degree (°) = 0.017453 radian (rad)
