How do i convert radians to degrees? is it pi/180 or 180/pi? i get them confused!

It could be either one, depending on whether you intend to multiply or divide.

When you convert, just remember that degrees ==> less radians,
and radians ==> more degrees.  Then you can always check the
results, and make sure that you used the right conversion factor
in the right direction.

Degrees = radians * 180/pi
