How to Convert Mils (NATO) to Circles

Protractors are often used to measure angle

To convert a mil measurement to a circle measurement, divide the angle by the conversion ratio. One circle is equal to 6,400 mils (NATO), so use this simple formula to convert:

circles = mils (NATO) ÷ 6,400

The angle in circles is equal to the mils (NATO) divided by 6,400.

For example, here's how to convert 5,000 mils (NATO) to circles using the formula above.
5,000 mil = (5,000 ÷ 6,400) = 0.78125 cir

Mils (NATO) and circles 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.

Circles

A circle is the equivalent of 1 revolution around a circle, or 360°.

A circle is sometimes also referred to as a revolution. Circles can be abbreviated as cir, for example 1 circle can be written as 1 cir.
