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.
Binary degree or binary radian (brad) is 1 turn/256. In terms of the SI unit radians this is π/128 rad. The binary degree is used in computing so that an angle can be efficiently represented in a single byte.
In relation to the base unit of [angle] => (radians), 1 Arcseconds (arcsec) is equal to 4.848137E-6 radians, while 1 Binary Degrees (b deg) = 0.0245436926 radians.| 1 Arcseconds | to common angle units |
