A turn is a unit of plane angle measurement equal to 2π radians, 360 degrees or 400 gradians. Subdivisions of a turn include half-turns, quarter-turns, centiturns, milliturns, etc. The closely related terms cycle and revolution are not equivalent to a turn, since these are not units of angle. See more A turn can be divided in 100 centiturns or 1000 milliturns, with each milliturn corresponding to an angle of 0.36°, which can also be written as 21′ 36″. A protractor divided in centiturns is normally called a "percentage See more The word turn originates via Latin and French from the Greek word τόρνος (tórnos – a lathe).
