This mil conversion reference table provides accurate conversion factors between mil and other angle units. All values are based on the NATO definition where 6400 mils = 360 degrees.
What is a Mil?
A mil (short for milliradian) is a unit of angular measurement used primarily in military applications for artillery and firearms. In the NATO standard, 1 mil is defined as 1/6400 of a full circle. This definition makes range estimation easier using the formula: distance to target (meters) = target size (meters) × 1000 ÷ mil reading.
Our mil conversion tool helps you easily convert between mils and other angle units. For example, 1 mil equals approximately 0.05625 degrees or 0.000981748 radians.
What is the Definition of Mil?
The mil is defined differently in various systems:
- NATO Mil: 1/6400 of a circle (most common)
- Soviet Mil: 1/6000 of a circle
- Swedish Mil: 1/6300 of a circle
This page uses the NATO definition (1 mil = 1/6400 circle) for all angle conversions.
What are Mils Used For?
Mils are used primarily in military applications, especially for range estimation, artillery targeting, and scope adjustments. Our mil conversion calculator is useful in several contexts:
Military Applications
Artillery targeting, range estimation, and weapon sight adjustments. For example, a tank gunner might use mils to adjust aim based on the observed target size and distance.
Firearms & Optics
Scope reticles and rangefinder measurements. For example, a sniper scope with mil-dot reticle markings allows for precise distance and windage calculations.
Surveying
Angular measurements in land surveying. For example, measuring the horizontal angle between two landmarks using a theodolite calibrated in mils.
Engineering
Precision angular measurements in mechanical engineering. For example, setting the angle of a machine tool head to within a few mils of a reference angle.
Etymology and History
The term "mil" is short for "milliradian," which is 1/1000 of a radian. The concept was first used in the early 20th century by military forces for artillery calculations. The milliradian was adopted because it provides a convenient approximation: at 1000 meters, 1 mil subtends approximately 1 meter.
Different military forces adopted slightly different definitions for practical reasons. The NATO standard of 6400 mils per circle was chosen for its divisibility and ease of use in calculations. This system allows for rapid mental calculations in field conditions, making it an essential tool for military angle measurements.
Frequently Asked Questions
What is the difference between mil and milliradian?
A mil is short for milliradian, but in practice, the term "mil" in military contexts refers to the NATO standard angular unit (1/6400 of a circle), which is slightly different from a true milliradian (1/1000 of a radian = 1/6283 of a circle). Our converter uses the NATO mil definition.
How do I convert mil to degrees?
To convert mil to degrees, multiply by 0.05625 (using the NATO definition). For example, 100 mils = 100 × 0.05625 = 5.625 degrees. Our mil conversion calculator provides instant conversions between mils and degrees with high precision.
What is the formula for range estimation using mils?
The basic range estimation formula is: Distance (meters) = Target Size (meters) × 1000 ÷ Mil Reading. For example, if a 2-meter tall target measures 4 mils in your scope, the distance is: 2 × 1000 ÷ 4 = 500 meters.
Why do different countries use different mil definitions?
Different definitions (NATO 6400, Soviet 6000, Swedish 6300) were adopted based on mathematical convenience and existing military practices. The NATO standard was chosen for its divisibility by many numbers (2, 4, 5, 8, 10, etc.), making mental calculations easier during military operations.
How accurate is mil-based range estimation?
Mil-based range estimation is quite accurate when used correctly, typically within 5-10% for experienced users. Accuracy depends on correctly estimating target size, precise mil reading, and environmental factors like atmospheric conditions. Our angle conversion tools help ensure precise unit conversions for these calculations.
Can I use mils for civilian applications?
Yes, mils are used in civilian applications such as surveying, engineering, and precision shooting sports. They provide a convenient angular measurement system for tasks requiring precise angle calculations. Whether you're a surveyor measuring land boundaries or a competitive shooter adjusting optics, our mil converter simplifies these tasks.
How does mil compare to MOA (Minute of Angle)?
Both mils and MOA are angular measurements, but 1 mil ≈ 3.44 MOA. Mils are based on the metric system (1/1000 radian approximation) while MOA is based on degrees (1/60 of a degree). Mils are generally preferred in military applications for easier calculations, while MOA is common in civilian shooting.
Is your mil conversion tool free to use?
Yes, our mil conversion calculator is completely free with no registration required. Simply enter your value, select your target unit, and get instant, accurate results. Whether you're a military professional, surveyor, or hobbyist, our angle converter tool makes mil conversions quick and simple.
