A) To convert radians to degrees

Multiply radians by 180 degrees/pi

Example:

3pi/4 ==> degrees

3pi/4 x 180 degrees/pi (pi will cancel out)

540/4 = 135 degrees

B) To convert degrees to radians

Multiply degrees by pi/180 degrees

Example:

60 degrees ==> radians

60 degrees x pi/180 degrees ( degrees will cancel out)

60pi/180 = pi/3
