How This Tool Works

This converter uses the NATO artillery mil convention where a full circle is divided into 6,400 mils. Since one full circle is 360°, 1 NATO mil equals 0.05625°.

To convert NATO mils to degrees, multiply the mil value by 360 / 6400, or 0.05625. To convert degrees back to NATO mils, divide the degree value by 0.05625.

For example, 1,600 NATO mils equals 90°, 3,200 NATO mils equals 180°, and 6,400 NATO mils equals 360°.

Why This Matters

NATO mils and degrees use different circle divisions, so treating the values as equal creates large bearing and elevation errors. Accurate conversion is useful when comparing military, surveying, navigation, mapping, and targeting references with standard degree measurements.

  • Navigation and mapping: Convert NATO mil bearings into degree-based compass or GIS values.
  • Surveying and field notes: Keep angular references consistent across tools.
  • Sanity checks: Remember that a right angle is 1,600 NATO mils, not 90 NATO mils.

Common Mistakes to Avoid

  • Do not divide by 10: 1 NATO mil is 0.05625°, not 0.1°.
  • Do not mix mil systems: NATO mils use 6,400 per circle, while USSR mils use 6,000 per circle.
  • Check full-circle values: 6,400 NATO mils should equal 360°.
