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 Nanoradians (nrad) is equal to 1.0E-9 radians, while 1 Second Of Arc (SOA) = 4.848137E-6 radians.89400 Nanoradians | to common angle units |
