1. What is MOA?

MOA (Minute of Angle) is an angular measurement used in shooting to describe rifle scope adjustments. One MOA equals 1.047 inches at 100 yards, though it's commonly simplified to 1 inch at 100 yards for practical purposes.

2. How Does the Calculator Work?

The calculator uses the MOA equation:

Where:

• \( Drop \) — Bullet drop in inches
• \( Distance \) — Shooting distance in yards

Explanation: The equation converts bullet drop at a given distance to MOA adjustments needed on your scope.

3. Importance of MOA Calculation

Details: Accurate MOA calculation is crucial for making precise scope adjustments at varying distances, especially in long-range shooting scenarios.

4. Using the Calculator

Tips: Enter drop in inches and distance in yards. All values must be valid (drop > 0, distance > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why divide distance by 100 in the formula?
A: MOA is standardized per 100 yards, so we normalize the distance to this base measurement.

Q2: What's the difference between MOA and MIL?
A: MOA uses minutes (1/60th of a degree) while MIL uses milliradians (1/1000th of a radian). 1 MIL ≈ 3.6 MOA.

Q3: How precise should my measurements be?
A: For best results, measure drop to at least 0.25 inch precision and distance to within 5 yards.

Q4: Does this account for environmental factors?
A: No, this is a basic calculation. Wind, temperature, and altitude will affect actual bullet trajectory.

Q5: Can I use this for metric measurements?
A: The calculator is designed for imperial units. For metric, convert cm to inches and meters to yards first.
