Shooting MOA Calculator
Calculate group size in MOA and MIL from a measured shot group size and shooting distance.
How to Use the Shooting MOA Calculator
- Measure your shot group size in inches (center-to-center of the two farthest holes).
- Enter the shooting distance in yards.
- Click Calculate to see group size in MOA, MIL, and centimeters at 100m.
使用场景
- •Evaluating rifle and ammunition accuracy at the range.
- •Comparing loads and rifle combinations by MOA performance.
- •Converting between angular measurement systems for scope adjustments.
公式
Formula: MOA = (group size inches / distance yards) × 100 / 1.0472. MIL = MOA / 3.4377. CM at 100m = MOA × 2.908.
常见问题
What is MOA in shooting?
MOA (Minute of Angle) is an angular measurement equal to 1/60 of a degree. At 100 yards, 1 MOA equals approximately 1.047 inches. It is the standard unit for describing rifle accuracy.
What is the difference between MOA and MIL?
MOA (1/60°) and MIL (milliradians, 1/1000 rad) are both angular units used for scope adjustments. 1 MIL = 3.44 MOA. Military scopes often use MIL; hunting scopes often use MOA.
What is a sub-MOA rifle?
A sub-MOA rifle consistently groups shots within 1 MOA (1.047 inches at 100 yards). This is considered an accuracy benchmark for precision rifles and quality ammunition.
