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 Second Of Arc (SOA) is equal to 4.848137E-6 radians, while 1 Rotations (rot) = 6.28319 radians.| 478000 Second Of Arc | to common angle units |
