Calculate MOA and Spread



Formula

To calculate the Minute of Angle (\(MOA\)):

\[ MOA = \frac{A}{60} \]

To calculate the Total Spread (\(S\)):

\[ S = MOA \times \frac{D}{100} \]

Where:

What is MOA?

MOA is short for minute of angle and is used to describe 1/60th of a degree. It is a measure used in shooting and ballistics to describe the accuracy and precision of a firearm or projectile.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ MOA = \frac{1}{60} \approx 0.0167 \]

\[ S = 0.0167 \times \frac{100}{100} = 0.0167 \text{ inches} \]

The Minute of Angle is approximately 0.0167 and the Total Spread is 0.0167 inches.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ MOA = \frac{2}{60} \approx 0.0333 \]

\[ S = 0.0333 \times \frac{200}{100} = 0.0666 \text{ inches} \]

The Minute of Angle is approximately 0.0333 and the Total Spread is 0.0666 inches.
