NATO Mils to Degrees Converter
Convert NATO mils to degrees — 6,400 mils to a full turn. Results update as you type; exact factors shown.
One NATO mil (1/6400 turn) is 0.0563 degrees — see the exact factor, not a rounded rule of thumb.
How the nato mils to degrees converter works
Angles convert through the radian. A full turn is 2π radians = 360° = 400 gon = 6,400 NATO mils. A degree is 60 arcminutes, an arcminute 60 arcseconds.
The UK is metric for most trade and science but keeps miles, pints, stone and mpg (with the imperial gallon) in daily life.

FAQFrequently asked questions about angle conversion
How many mils in a full turn?
6,400 in the NATO system.
What is a mil?
A milliradian approximation chosen so a turn divides into a round 6,400 — one mil subtends about one metre at a thousand.
Why not use true milliradians?
A true milliradian gives 6,283.19 to a turn, which is awkward. NATO rounded to 6,400 for arithmetic in the field.
What is 1,600 mils?
Ninety degrees — a right angle.
Do all militaries use 6,400?
No. Warsaw Pact systems used 6,000, and Sweden used 6,300. The difference matters when sharing fire data.
