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 US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.

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 meter 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.
