how do you convert degrees to radians?

One degree is equal 0.01745329252 radians:1° = π/180° = 0.005555556π = 0.01745329252 radThe 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°orradians = degrees × π / 180°ExampleConvert 30 degrees angle to radians:α(radians) = α(degrees) × π / 180° = 30° × 3.1459 / 180° = 0.5236 radDegrees to radians in terms of piThe angle α in radians is equal to the angle α in degrees times pi constant divided by 180 degrees:α(radians) = (α(degrees) / 180°) × πExampleConvert 30 degrees angle to radians in terms of pi:α(radians) = (α(degrees) / 180°) × π = (30° / 180°) × π = (1/6) × π = π/6 rad = 0.166667π rad
