Arcsecond
An arcsecond (second of arc), represented by the symbol ,[1] is a unit of angle used in mathematics and astronomy. An arcsecond is 1/60th of an arcminute (minute of arc),[2] which in turn is 1/60th of a degree.[3] Therefore, an arcsecond is equal to 1/3600th of a degree,[2] meaning that there are 360 × 60 × 60 = 1,296,000 arcseconds in a full circle.
