Unit definitions
- Radian (rad)
- The radian is the SI unit of angle: the angle at the center of a circle subtended by an arc equal in length to the radius. A full turn is 2π radians, so one radian is 180/π degrees, about 57.2958°.
- Arcsecond (″)
- An arcsecond, or second of arc, is 1/60 of an arcminute, or 1/3600 of a degree. It is used in astronomy and precise surveying.
