You can put this solution on YOUR website!
radians = degrees * pi / 180

degrees = radians * 180 / pi.

you have 120 degrees.

radians = 120 * pi / 180 which is equal to 120 / 180 * pi which is equal to 12/18 * pi radians which is equal to 2 / 3 * pi radians.

radians is equal to pi.

degrees = radians * 180 / pi.

degrees = pi * 180 / pi which is equal to 180 degrees.

remember those 2 formulas and you should not have any trouble converting from one to the other.
