Pi radians are equal to 180 degrees:

π rad = 180°

One degree is equal 0.01745329252 radians:

1° = π/180° = 0.005555556π = 0.01745329252 rad

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

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

or

radians = degrees × π / 180°

Convert 30 degrees angle to radians:

α_{(radians)} = α_{(degrees)} × π / 180° = 30° × 3.1459 / 180° = 0.5236 rad
