→Units: Add arcminute and arcsecond
Radian: Most commonly used in science and engineering, is the angle subtended by an arc of a circle which have the same length as the circle radius. One full circle is equal to 2<big><math>\pi</math></big> radians, and one radian is 180/<big><math>\pi</math></big> degrees.

Arcminute: Commonly used in [[astronomy]], 1 arcminute is 1/60 of a degree or 1/21600 of a circle. It is useful due to the small angles often encountered.
Arcsecond: Commonly used in [[astronomy]], 1 arcminute is 1/60 of an arcminute or 1/1296000 of a circle.
