An angle of 1 radian subtends an arc equal in length to the radius of the circle. The full circle has a radius of 2 pi, thus the measure of the angle of a circle is 2 pi radians.
1 radian = 180 degrees / pi or about 57.2958 degrees.

The radian, in mathematics, is a unit of plane angle, equal to 180/π degrees, or about 57.2958 degrees. It is represented by the symbol "rad" or, more rarely, by the superscript c (for "circular measure"). For example, an angle of 1.2 radians would be written as "1.2 rad" or "1.2c" (the second symbol can be mistaken for a degree: "1.2°").
