Arcmin also known as arc minute or minute arc is a unit of angular measurement. One minute of arc is equal to 1/21600 of a turn. That means one full circle will have 21600 arcminutes. This unit was originated in Babylonian astronomy as sexagesimal subdivisions of the degree. It is primarily used in fields where most of the work involves working with small angles such as optometry, ophthalmology, and astronomy. In astronomy related work, it is used for comparison of angular diameter of Moon, Sun, and planets. Apart from that, it is also used in cartography and navigation. The symbol for Arcmin is arcmin.
Use this Arcmin converter to change values into other angle units. Enter a value, choose the target unit, and review the converted result without applying the conversion factor by hand.
It is useful when a measurement is recorded in Arcmin but a formula, specification, or comparison requires another angle unit. The available target units are listed below the example and conversion table.
Arcmin is one of the units available in this angle category. Use the result as a reference, and retain suitable precision when the value will be used in a technical or scientific calculation.
The calculator formats results for readability. Display rounding can affect the last digits, so check the original input and the shown precision before copying a result into a report or further formula.
