How to switch degrees over completely to radians

Pi radians are equivalent to 180 degrees:

π rad = 180°

One degree is equal 0.01745329252 radians:

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

The point α in radians is equivalent to the point α in degrees times pi steady partitioned by 180 degrees:

α(radians) = α(degrees) × π/180°

or

radians = degrees × π/180°

Example

Convert 30 degrees point to radians:

α(radians) = α(degrees) × π/180° = 30° × 3.14159/180° = 0.5236 rad
