An arcminute (arcmin) or minute of arc 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 Hour Angles (HA) is equal to 0.26179938779 radians, while 1 Arcminutes (arcmin) = 0.000290888 radians.| 422500 Hour Angles | to common angle units |
