The radian is the SI unit (symbol rad) of plane angles, an alternative unit to the degree. It is the angle at the centre of a circle when the centre is joined to the two ends of an arc equal in length to the radius of the circle. There are 2 pi (approximately 6.284) radians in a full circle (360 degrees). One radian is approximately 57 degrees, and 1 degree is pi/180 or approximately 0.0175 radians. Radians are commonly used to specify angles in polar co-ordinates.
