Grad : The grad, also known as gadian, gon or grade is a measure unit of plane angle equal to 9/10 of a degree or π⁄200 of a radian.
Radian : The radian is the standard unit of angle which is defined as the ratio between the length of an arc and its radius. It is an SI derived unit, commonly used in many areas of mathematics. One radian is approximately equal to 57.3 degrees. Its symbol is rad, an alternative symbol is the superscript letter c which is infrequently used as it can be easily mistaken for a degree symbol (°).
