About these units

Minute: An arcminute (minute of arc) is 1/60 of a degree.It is used in astronomy, optics, navigation, geodesy, and surveying for small angular measurements.

Radian: The radian (rad) is the SI derived unit of plane angle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius.Although mathematically dimensionless, th...
