MOA calculator minute of angle

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:

\(MOA\) is the Minute of Angle
\(S\) is the Total Spread (inches)
\(D\) is the Total Horizontal Distance (yards)

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:

Angle (\(A\)) = 1 degree
Distance (\(D\)) = 100 yards

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:

Angle (\(A\)) = 2 degrees
Distance (\(D\)) = 200 yards

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.
