Enter the total angle into the calculator to determine the MOA as well as the total spread.
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 )
MOA is short for minute of angle and is used to describe 1/60th of a degree.
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.
A minute of angle is described as 1/60th of a degree. This term is often used in fields such as shooting and archery.
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.
