Convert Arc Minute to Mil (arcminute to Mil)

Arc Minute (arcminute) and Mil (Mil) are both units of angle. With the conversion form below, you can effortlessly and accurately convert arc minute to mil. This free online calculator tool makes it simple and easy to perform the conversion from arcminute unit to the Mil unit.

An angle is a measure of the rotation between two rays that share a common endpoint (vertex). The most common unit is the degree (°), where a full circle = 360°. The SI-derived unit is the radian (rad), where a full circle = 2π rad ≈ 6.2832 rad; one radian is the angle subtended at the centre of a circle by an arc equal in length to the radius. Other units include the gradian (grad) (400 grad = full circle) and the arcminute (′) and arcsecond (″), widely used in astronomy and navigation.

A minute of arc (arcminute, or minute) is an angular unit equal to 1/60 of a degree, or 1/21,600 of a full circle. Arcminutes are standard in astronomy, navigation, and precision measurement of angles. Astronomers measure the angular separation of celestial objects in degrees and arcminutes. GPS and navigation systems reference latitude and longitude in degrees and minutes (though decimal degrees are increasingly common). The arcminute derives from ancient astronomical divisions of the circle and remains embedded in geographic coordinates, telescopic measurements, and scientific precision work. The term "minute" comes from medieval Latin meaning "small division," distinguishing it from the minute of time despite the identical terminology.

A mil (military mil, also called NATO mil or angular mil) is a unit of angular measurement equal to 1/6,400 of a full circle, or approximately 0.05625 degrees. The mil was designed for military targeting and ballistics calculations, where 1 mil at 1,000 meters corresponds to approximately 1 meter of linear distance—making rapid field adjustments practical. Artillery spotters, surveyors, and firearms specialists use mils for angle measurements in targeting, reconnaissance, and precision work. The unit appears in rifle scope adjustments, military maps, and ballistic tables. Different military traditions have developed slightly different mil definitions (Soviet mil, Swedish mil), but NATO mil remains the most widely standardized version in international military and surveying contexts.
