## How to Convert Seconds Of Arc to Mils (NATO)

To convert a second of arc measurement to a mil measurement, multiply the angle by the conversion ratio. One second of arc is equal to 0.004938 mils (NATO), so use this simple formula to convert:

The angle in mils (NATO) is equal to the seconds of arc multiplied by 0.004938.

**For example,**here's how to convert 5 seconds of arc to mils (NATO) using the formula above.

Seconds of arc and mils (NATO) are both units used to measure angle. Keep reading to learn more about each unit of measure.

## Seconds Of Arc

The second of arc is a unit of angle equal to 1/60th of one minute of arc or 1/3,600 of one degree.

A second of arc is sometimes also referred to as an arc second or arcsecond. Seconds of arc can be abbreviated as *arcsec*, and are also sometimes abbreviated as *asec*. For example, 1 second of arc can be written as 1 arcsec or 1 asec.

The second of arc is most commonly expressed using a double prime (″), though a double quote is often used as well. For example, 1 second of arc is most often written as 1″.

## Mils (NATO)

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 (NATO) can be abbreviated as *mil*, for example 1 mil can be written as 1 mil.
