A minute of arc or arcminute (arcmin) is a unit of angular measurement equal to 1/60 of one degree. Since one degree is 1/360 of a turn (or complete rotation), one minute of arc is 1/21600 of a turn (or, in radians, π/10800).
In relation to the base unit of [angle] => (radians), 1 Microarcseconds (μas) is equal to 4.8481368E-12 radians, while 1 Minute Of Arc (MOA) = 0.000290888 radians.| 1 Microarcseconds | to common angle units |
