Description:

The radian is an SI derived unit of angle, commonly used in maths and engineering. A radian measures approx. 56.296 degrees (when the arc length is equal to the radius). A centrad is 1/100th of a radian.

Definition:

The angle made by taking the radius of a circle and wrapping it along the circle's edge. Therefore 1 Radian is equal to (180/π) degrees and a Centrad= (180/π)*100

Origin:

Roger Cotes, a colleague of Isaac Newton who helped proofread the Principia, is credited with defining the radian in 1714, although other mathematicians had been using angle measurements based on the length of the arc as far back as the 15th Century
