Second, Angle

A second of arc, arcsecond, or second arc (SOA), is a unit of angular measurement equal to one sixtieth (1⁄60) of one minute of arc. Since one minute of arc is defined as 1⁄21600 of a rotation, one second of arc is 1⁄1296000 of a rotation. It is used in those fields which require a unit for the expression of small angles, such as astronomy, navigation and marksmanship.Read more
