Convert from 1/2 circle to minute

Unit Definition (1/2 circle)

Unit Definition (minute)
The minute is a unit of angular measure equal to 60 arcseconds or to 1/60 degree. This unit is often called the arcminute to distinguish it from the minute of time. There are 21 600 arcminutes in a circle. The SI defines min as the symbol for the time unit and recommends ' as the symbol for the arcminute. The symbol moa ("minute of angle") is often used in target shooting. The international standard ISO 31 requires that angles be stated in degrees and decimal fractions of the degree, without use of arcminutes and arcseconds.
