An arcsecond (arsec) or second of arc 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 Arcseconds (arcsec) is equal to 4.848137E-6 radians, while 1 Centesimal Minute Of Arc (c MOA) = 0.00015708 radians.| 1 Arcseconds | to common angle units |
