A Radian is a unit that only exists in a circuit.
It is used to describe an angle that is equal to the arc length divided by the radius.
PI Rad is equal to 180 degrees. Rad is a way to write a degree including PI.

Here you can see that the formula for circumference of a circle is just what the rad of the hole circle is.
I prefer degrees because it is not written as a fraction and you emediatly know how it would look on circle. For example: 192 degrees -> Ok that's a little more then half way around.; 16pi/15 Oh great now i know more.
