A second of arc, or arcsecond (arsec) is 1/60 of an arcminute, 1/3600 of a degree, 1/1296000 of a turn, and π/648000 (about 1/206265) of a radian.
In relation to the base unit of [angle] => (radians), 1 Hour Angles (HA) is equal to 0.26179938779 radians, while 1 Second Of Arc (SOA) = 4.848137E-6 radians.| 3566000000 Hour Angles | to common angle units |
