How do i express angles in a radian measure as multiples of pi.

For example, suppose i have an angle of 30 degrees, and a angle of -270 degrees. How would I express them in a radian measure as a multiple of pi?.

Thanks.

  1. 180 degrees is pi radians.
    That is all you have to remember.
    For example to convert 30 degrees to radians:

    30 degrees * ( pi radians / 180 degrees) = pi/6 radians
