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.
The radian (symbol rad) is the standard unit of angular measure. The radian is determimed by the circumference of a circle that is equal in length to the radius of the circle. ..more definition+
