Moa To Inches Formula

The following formula is used to calculate the conversion from MOA to inches.

I = MOA * D / 100 * 1.047

Variables:

  • I is the size of the shot group in inches MOA is the Minute of Angle
  • D is the distance to the target in yards

* Rounded to 3 decimals. Formula: size (in) = MOA × distance (yd) × 1.047 ÷ 100. True MOA: 1 MOA ≈ 1.047 inches at 100 yards.

What is a Moa To Inches?

A MOA (Minute of Angle) to inches is a measurement conversion used in shooting and ballistics. It is a unit of angular measurement equal to 1/60th of one degree. In practical terms, a MOA is approximately equal to 1 inch at 100 yards, 2 inches at 200 yards, and so on. This conversion is often used to adjust rifle scopes for improved accuracy.

How to Calculate Moa To Inches?

The following steps outline how to calculate the Moa To Inches using the formula: I = MOA * D / 100.


  1. First, determine the Minute of Angle (MOA).
  2. Next, determine the distance to the target in yards (D).
  3. Next, use the formula I = MOA * D / 100 to calculate the size of the shot group in inches (I).
  4. Finally, calculate the Moa To Inches.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Minute of Angle (MOA) = 3

Distance to the target in yards (D) = 500
