How many radians are in 180 degrees?

Explanation:
Radians scale with the circle: a full turn is 2pi radians and 360 degrees. Half a turn, 180 degrees, is half of 2pi, which is pi radians. You can also convert directly using radians = degrees × pi/180; for 180 degrees this gives 180 × pi/180 = pi. So the amount of radians in 180 degrees is pi.
