MOA Formula:
From: | To: |
MOA (Minute of Angle) is an angular measurement used in shooting to describe accuracy and precision. One MOA equals approximately 1 inch at 100 yards, with the measurement increasing proportionally with distance.
The calculator uses the MOA formula:
Where:
Explanation: The formula calculates how many MOA a given measurement represents at a specific distance, normalizing the measurement to the standard 100-yard reference.
Details: MOA calculation is essential for precision shooting, scope adjustment, and understanding firearm accuracy. It helps shooters make precise adjustments to hit targets at various distances.
Tips: Enter the measurement in inches and the distance in yards. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What does 1 MOA represent?
A: 1 MOA equals approximately 1 inch at 100 yards, 2 inches at 200 yards, and so on, increasing linearly with distance.
Q2: How is MOA used in scope adjustments?
A: Most rifle scopes adjust in MOA increments (typically 1/4 MOA per click), allowing precise aiming corrections based on distance and windage.
Q3: What's the difference between MOA and MIL?
A: MOA uses minutes of angle (1/60th of a degree) while MIL uses milliradians (1/1000th of a radian). Both are angular measurements but use different base units and calculations.
Q4: Can MOA be converted to metric measurements?
A: Yes, MOA can be converted to centimeters or millimeters at metric distances, though the standard reference remains 100 yards (approximately 91.44 meters).
Q5: Why is MOA preferred by many shooters?
A: MOA provides finer adjustments than MIL systems (1/4 MOA ≈ 0.26" at 100yd vs 1/10 MIL ≈ 0.36" at 100yd), making it popular for precision shooting where minute adjustments matter.
