1. What is Minute of Angle (MOA)?

Minute of Angle (MOA) is an angular measurement used in ballistics to describe the accuracy of firearms and make scope adjustments. One MOA equals approximately 1 inch at 100 yards, with this value increasing proportionally with distance.

2. How Does the Calculator Work?

The calculator uses the MOA formula:

Where:

• \( Inches \) — Deviation or group size in inches
• \( Yards \) — Distance to target in yards

Explanation: This formula calculates how many minutes of angle your shot deviation represents at a given distance, allowing for precise scope adjustments.

3. Importance of MOA Calculation

Details: Accurate MOA calculation is essential for long-range shooting, scope calibration, and making precise adjustments to hit targets consistently at various distances.

4. Using the Calculator

Tips: Enter your shot deviation in inches and the distance to target in yards. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: How precise is 1 MOA?
A: 1 MOA equals approximately 1.047 inches at 100 yards, but for practical purposes, it's often rounded to 1 inch at 100 yards.

Q2: How does MOA relate to MILs?
A: MOA and MIL (milliradian) are different angular measurements. 1 MIL equals approximately 3.6 inches at 100 yards, while 1 MOA equals approximately 1 inch at 100 yards.

Q3: Why is MOA important for scope adjustments?
A: Most rifle scopes have turrets calibrated in MOA increments, allowing shooters to make precise adjustments based on calculated MOA values.

Q4: Does MOA change with distance?
A: While the angular measurement remains constant, the linear measurement increases with distance (e.g., 1 MOA ≈ 1 inch at 100 yards, ≈ 2 inches at 200 yards, etc.).

Q5: Can I use this calculator for metric measurements?
A: This calculator is designed for imperial measurements (inches and yards). For metric, you would need to convert to centimeters and meters first.
