How to convert radians to degrees 
Know that π radians is equal to 180 degrees. 
Before you begin the conversion process, you have to know that π radians = 180 °, which is equivalent to going halfway around a circle. This is important because you'll be using 180/π as a conversion metric.
This is because 1π radians is equal to 180/π degrees. Multiply the radians by 180/π to convert to degrees.
