A minute of arc (MOA), arcminute (arcmin) or minute arc is a unit of angular measurement equal to one-sixtieth (1â60) of one degree. As one degree is 1â360 of a circle, one minute of arc is 1â21600 of a circle (or, in radians, Ïâ10800). It is used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying and marksmanship.
