About these units
The degree divides a circle into 360 parts. Draft angles, chamfers, and index positions on drawings are dimensioned in degrees.
The radian is the SI angle, the angle subtending an arc equal to the radius. Motion control math and angular velocity use radians; a full circle is 2 pi radians.
