1 radian = 57.3R degrees
The degree is a measurement unit of angles. A complete circle is divided into 360 degrees.
One degree is equal 0.01745329252 radians.
1° = π/180° = 0.005555556π = 0.01745329252 rad
Radians to Degrees conversion
The general formula to convert radian into degree is to simply multiply the given number of degrees by 180°/ π.
