What is 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.

Example Calculation

Let's assume the following values:

Using the formula:

\[ I = \left( 1 \times 200 \right) / 100 = 2 \text{ inches} \]

The size of the shot group is 2 inches.
