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 Microarcseconds (μas) is equal to 4.8481368E-12 radians, while 1 Arcseconds (arcsec) = 4.848137E-6 radians.49 Microarcseconds | to common angle units |
