Minute of Angle : 1 moa = 1/60 of a degree : 1 moa is 1.047 inches at 100 yards. A minute of arc, arcminute, or minute arc (MOA), is a unit of angular measurement equal to one sixtieth (1⁄60) of one degree. In turn, a second of arc or arcsecond is one sixtieth (1⁄60) of one arcminute. Because one degree is defined as one three hundred and sixtieth (1⁄360) of a rotation, one minute of arc is 1⁄21,600 of a rotation, which also equals π⁄10,800 radians. It is used in those fields that require a unit for the expression of small angles, such as astronomy, optometry, ophthalmology, optics, navigation and marksmanship
