How to convert degrees to radians

One degree is equal, in radians, to:

1° = π/180º = 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 / 180º

Example

Convert 30 degrees (30°) angle to radians:

α(radians) = α(degrees) × π / 180º = 30º × 3.1459 / 180º = 0.5236 rad
