Mrad Calculator

If you’re a long-range shooter, hunter, or military marksman, you’ve probably heard of MRAD (Milliradian). Estimating the distance to a target is one of the most critical skills in precision shooting. However, doing the math manually can be time-consuming and prone to error — and that’s where our online MRAD Calculator comes in.

This tool is designed to help you calculate target distance in meters quickly and accurately using the MRAD formula. By simply entering your target size (in centimeters) and the mils (MRAD) reading from your scope, you’ll instantly get the calculated range — no need for a physical calculator or complex math.

In this article, we’ll explain what MRAD is, how to use the MRAD calculator, show real-world examples, and answer common questions to help you get the most out of this tool.

🔍 What is MRAD (Milliradian)?

MRAD stands for milliradian, a unit of angular measurement used by shooters and snipers to calculate distances and make precise scope adjustments. One radian equals about 57.3 degrees, and one milliradian (mrad) equals 1/1000th of a radian.

In practical shooting terms:

  • 1 MRAD equals 10 centimeters at 100 meters
  • MRAD is used to estimate target range when you know the target’s actual size and how large it appears through your optic (in mils)

This measurement system is preferred by professionals because it provides consistent and precise adjustments, especially for long-range shooting or sniping.

🧮 How the MRAD Calculator Works

The MRAD formula is straightforward but easy to mix up under pressure. Here’s the base formula:

Range (m) = (Target Size (cm) × 1000) / MRAD

Let’s break it down:

  • Target Size (cm): The actual height or width of the target in centimeters.
  • MRAD (Mils): The angular measurement seen through your scope.
  • Range (m): The distance to your target in meters.

The MRAD calculator simplifies this process — just input the two known values, and the tool computes the range automatically.

⚙️ How to Use the MRAD Calculator

Using our MRAD Calculator is extremely simple. You don’t need any technical knowledge or complex software.

Step-by-Step Guide:

  1. Enter Target Size (cm):
    Measure or estimate your target’s actual height or width in centimeters. For example, if the target is a person standing 180 cm tall, enter 180.
  2. Enter MRAD (Mils):
    Look through your rifle scope or spotting scope and determine how many mils the target covers. For instance, if the target spans 3.6 mils, enter 3.6.
  3. Click "Calculate":
    The tool will instantly calculate and display the Range (in meters) based on the MRAD formula.
  4. View the Result:
    The calculated distance will appear in the “Range” field. You can now use this information for accurate shooting or ranging adjustments.
  5. Reset if Needed:
    To perform another calculation, simply click the Reset button, and the fields will clear for a new entry.

🎯 Example Calculation

Let’s see how it works with a real-world example:

  • Target Size: 180 cm (average human height)
  • MRAD (Mils): 3.6

Formula:
Range = (180 × 1000) / 3.6 = 50,000 / 3.6 = 500 meters

✅ Result: The target is approximately 500 meters away.

This is a fast and reliable way to get your range without needing a rangefinder or complex math on the fly.

💡 Why Use an MRAD Calculator?

Here are a few reasons why shooters and professionals use this tool:

  • Accuracy: Provides precise distance measurements.
  • Speed: Instant results — no manual calculations required.
  • Convenience: Accessible from any device, anywhere.
  • Consistency: Eliminates human error in range estimation.
  • Versatility: Useful for shooters, hunters, military, and even surveyors.

🧠 Understanding the MRAD Formula

The MRAD formula essentially converts angular measurements into linear distance.
When you look through your scope, you see the target occupying a certain number of mils. Using that number and knowing the target’s real size, you can back-calculate the range.

Because 1 MRAD = 1 meter at 1000 meters, multiplying the target size (in cm) by 1000 and dividing by the observed mils gives the range in meters.

This formula is universal and works with any magnification system calibrated in MRAD.
