#### Radians and Degrees

Radians and degrees are both units used for measuring angles. As you may know, a circle is comprised of 2π radians, which is the equivalent of 360°; both of these values represent going "once around" a circle. Therefore, 1π radian represents going 180° around a circle, which makes 180/π the perfect conversion tool for moving from radians to degrees. To convert from radians to degrees, you simply have to multiply the radian value by 180/π.

#### How to convert radians to degrees

Pi radians are equal to 180 degrees:

π rad = 180°

One radian is equal 57.295779513 degrees:

1 rad = 180°/π = 57.295779513°

The angle α in degrees is equal to the angle α in radians times 180 degrees divided by pi constant:

α_{(degrees)} = α_{(radians)} × 180° / π

or

degrees = radians × 180° / π

#### Example:

Convert 2 radians angle to degrees:

α_{(degrees)} = α_{(radians)} × 180° / π = 2 × 180° / 3.14159 = 114.592°
