MOA Adjustment Calculator

One true minute of angle covers 1.047 inches at 100 yards. Many shooters round this to 1 inch, but this calculator uses the precise 1.047 value so the error does not stack up as distance grows.

Inches equals MOA times 1.047 times distance in yards divided by 100. For 2 MOA at 200 yards that is 2 x 1.047 x 2, which is 4.188 inches of movement at the target.

Clicks equal the MOA value divided by your turret click value. On a common quarter MOA turret, 2 MOA is 2 divided by 0.25, which is 8 clicks. Change the click value in the menu to match your scope.

True MOA is 1.047 inches at 100 yards, the actual angular value. Shooter MOA, sometimes called inch MOA, rounds to exactly 1 inch at 100 yards. The gap widens with range, so this tool sticks with true MOA.

Read it off your turret. Most hunting and target scopes adjust in quarter MOA, so 1/4. Some precision turrets use 1/8 MOA for finer control, and some older or long range models use 1/2 MOA. Pick the one printed on your dial.

No. This tool is built around minute of angle turrets. Mil based scopes use a different unit where one mil is 3.6 inches at 100 yards, so a MOA figure will not map to mil clicks correctly.

Yes. MOA is just an angle, so the same math applies whether you are dialing elevation to raise the point of impact or windage to move it sideways. Enter the correction you measured in either axis.

The result is the exact division of MOA by click value, shown to two decimals. If it lands between clicks, such as 2.50 clicks, your turret cannot split a click, so round to the nearest whole click when you dial.
