## MOA Formula

The following formulas are used to calculate the MOA and spread respectively.

MOA = A / 60

S = MOA * D / 100

- Where MOA is the minute of angle
- S is the total spread (inches)
- D is the total horizontal distance (yards)

To calculate a minute of angle, divide the spread by the distance, then multiply by 100.

## MOA Definition

MOA is short for minute of angle and is used to describe 1/60th of a degree.

## MOA Example

How to calculate MOA?

**First, determine the absolute angle.**Measure the total angle in degrees.

**Next, calculate the MOA.**Calculate the minute of angle using the formula above.

## FAQ

**What is a MOA?**

A minute of angle is described as 1/60th of a degree. This term is often used in fields such as shooting and archery.

**What is spread?**

Spread is the amount of vertical distance an angle causes at a certain horizontal distance. For example, 1 MOA at 100 yards is approximately 1″ of vertical spread, while at 200 yards it’s close to 2″ of vertical spread.
