How to Convert Revolutions to Mils (NATO)

Protractors are often used to measure angle

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

mils (NATO) = revolutions × 6,400

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

For example, here's how to convert 5 revolutions to mils (NATO) using the formula above.
5 r = (5 × 6,400) = 32,000 mil

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


A revolution, or turn, is equal to 1 rotation around a circle, or 360°. Revolutions are commonly used to measure the speed of rotation, for example when measuring the revolutions per minute (RPM) of a vehicle's engine.

A revolution is sometimes also referred to as a turn, cycle, or complete rotation. Revolutions can be abbreviated as r, and are also sometimes abbreviated as rev or cyc. For example, 1 revolution can be written as 1 r, 1 rev, or 1 cyc.

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.
