Plane angle Units

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.


Radian

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.


Grad

Grad unit or gradian unit is a unit of a plane angle, defined as one-hundredth of the right angle there are 100 gradians in 90 degrees. The gradian other names the gon, grad, or grade.


Grad to Radian Formula
