About Milliradians

A milliradian (mil) is an angular measurement unit used in artillery, surveying, and shooting sports. Different organizations use slightly different definitions:

Common Milliradian Standards
  • NATO: 6400 mils = 360° (used by NATO countries)
  • Warsaw Pact/Soviet: 6000 mils = 360° (used by former Warsaw Pact countries)
  • True Milliradian: 2π × 1000 ≈ 6283.18 mils = 360° (based on true radian measure)
Uses of Milliradians
  • Artillery fire control and adjustment
  • Sniper and precision shooting
  • Land surveying and navigation
  • Range estimation using the mil-dot reticle
Practical Application

The mil-relationship formula allows for quick field calculations:
Size in meters = (Size in mils × Distance in kilometers) ÷ 1000

This is useful for range estimation and target sizing in military and shooting applications.

Degrees to NATO milliradians:
mils = degrees × (6400 ÷ 360)

NATO milliradians to degrees:
degrees = mils × (360 ÷ 6400)

What Is the Degrees to Milliradians Calculator?

The Degrees to Milliradians Calculator is a handy unit conversion tool that helps you quickly convert angle measurements between degrees and milliradians (mils). This angle conversion tool is especially useful in fields like artillery, surveying, and long-range shooting where angles need to be calculated with high precision.

Milliradians are commonly used in scopes, targeting systems, and range estimation. Since there are multiple standards for milliradians—like NATO (6400 mils), Warsaw Pact (6000 mils), and True Milliradians (6283.18 mils)—this calculator allows you to choose the right conversion formula based on your application.

How to Use the Calculator

This measurement converter is simple to use and delivers accurate results fast. Here's how you can use it:

  • Select the conversion type: Degrees to Milliradians or Milliradians to Degrees.
  • Choose the mil standard: NATO, Warsaw Pact, Soviet Union, or True Milliradians.
  • Enter the value you want to convert in the corresponding input field.
  • Set the number of decimal places you want to display.
  • Click “Convert” to see the results instantly.
  • Use the “Reset” button to clear all fields and start a new calculation.

Key Features

  • Supports four different mil standards
  • Allows conversions in both directions (degrees ↔ mils)
  • Option to display the conversion formula and steps
  • Selectable decimal precision
  • Displays equivalent values in Other mil systems for better context

Why Use This Conversion Tool?

Whether you're adjusting a rifle scope, plotting artillery angles, or making precise survey measurements, this tool serves as a conversion helper to ensure accuracy. It saves time and avoids manual errors by providing quick unit conversions you can trust.

Because it includes multiple standards, it's suitable for professionals and enthusiasts working with different systems around the world. It's also great for anyone learning about angular units and needing a degree conversion guide or mrad to degree tool.

Frequently Asked Questions (FAQ)

What is a milliradian?

A milliradian (mil or mrad) is a unit of angular measurement. It represents 1/1000 of a radian. In practical use, it helps measure angles in scopes, targeting equipment, and surveying instruments.

How many milliradians are in a circle?

That depends on the standard:

  • NATO: 6400 mils = 360°
  • Warsaw Pact / Soviet: 6000 mils = 360°
  • True Milliradians: Approximately 6283.18 mils = 360°

Can I use this as a Degrees to Radians Calculator?

This tool specifically converts between degrees and milliradians. For degrees into radians or radians to degrees conversion, you can use a dedicated radian conversion guide or calculator.

Is this calculator suitable for field use?

Yes. It’s built for ease and speed. It’s particularly useful in the field for applications like range estimation, artillery targeting, and shooting where precise angle calculations matter.

Conclusion

This Degrees to Milliradians Calculator is a practical measurement converter for professionals and hobbyists alike. With its intuitive interface and multiple standards, it makes mrad from degrees or mrad to degrees conversion fast, accurate, and reliable. It's the conversion tool you didn’t know you needed—until now.
