How to Convert Mils to Minutes of Arc

To convert a measurement in mils to a measurement in minutes of arc, multiply the angle by the following conversion ratio: 3.375 minutes of arc/mil.

Since one mil is equal to 3.375 minutes of arc, you can use this simple formula to convert:

minutes of arc = mils × 3.375

The angle in minutes of arc is equal to the angle in mils multiplied by 3.375.

For example, here's how to convert 5 mils to minutes of arc using the formula above.

minutes of arc = (5 mil × 3.375) = 16.875'

What Is a Mil?

A mil, short for milliradian, is equal to 1/6,400 of a circle. The mil used by the US military and NATO forces is slightly different than the true value of a milliradian, which is equal to 1/6,283 of a circle.

During World War I the US adopted what is now the NATO mil to replace degrees and minutes for use in artillery sights. They opted to round mils to 6,400 per circle for simplicity at the time. Today, the mil is commonly used to measure adjustment of sights and scopes of firearms.

There is rightfully much confusion as a result of the mil adopted by the US military and NATO being slightly different than the milliradian.

A mil is sometimes also referred to as an angular mil. Mils can be abbreviated as mil; for example, 1 mil can be written as 1 mil.

A minute of arc is sometimes also referred to as an arc minute, arcminute, or minute arc. Minutes of arc can be abbreviated as arcmin, and are also sometimes abbreviated as MOA or amin. For example, 1 minute of arc can be written as 1 arcmin, 1 MOA, or 1 amin.
