About the units
Radians (rad)
The radian (rad) is the SI unit of angle: the angle whose arc equals the radius. A full circle is 2π radians, and maths and programming functions use radians.
Degrees (°)
A degree (°) is 1/360 of a full circle. A right angle is 90°, and each degree divides into 60 arcminutes.
