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

To convert a mil measurement to a second of arc measurement, multiply the angle by the conversion ratio. One mil is equal to 202.5 seconds of arc, so use this simple formula to convert:

The angle in seconds of arc is equal to the mils (NATO) multiplied by 202.5.

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

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

## 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.

## 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″.
