Arcminutes
Symbol: '
In geometry and trigonometry, an angle (in full, plane angle) is the figure formed by two rays sharing a common endpoint. Units of angular measurement are defined such that one full circle (i.e. one revolution) is equal to n units, for some whole number n.
One full circle is 360 degrees. A minute of arc or arcminute (MOA) is a unit of angular measurement, equal to one sixtieth (1/60) of one degree. Therefore one full circle is 21600 arcminutes.
