What is MOA?
Minute of Angle (MOA) is an angular measurement used in shooting and ballistics. One MOA equals 1/60th of a degree. At 100 yards, 1 MOA equals approximately 1.047 inches (commonly rounded to 1 inch for practical purposes).
MOA is the standard unit for rifle scope adjustments in the United States and is crucial for precision shooting at various distances.
MOA to Inches Conversions
| Distance | 1 MOA | 2 MOA | 5 MOA | 10 MOA |
|---|---|---|---|---|
| 100 yards | 1.047 in | 2.094 in | 5.235 in | 10.47 in |
| 200 yards | 2.094 in | 4.188 in | 10.47 in | 20.94 in |
| 300 yards | 3.141 in | 6.282 in | 15.71 in | 31.41 in |
| 500 yards | 5.235 in | 10.47 in | 26.18 in | 52.35 in |
| 1000 yards | 10.47 in | 20.94 in | 52.35 in | 104.7 in |
Scope Click Adjustments
Most rifle scopes have turrets that adjust in 1/4 MOA increments per click. This means:
- 4 clicks = 1 MOA adjustment
- 1 click at 100 yards = approximately 0.25 inches
- 1 click at 200 yards = approximately 0.50 inches
- 8 clicks = 2 MOA adjustment
Some scopes use 1/2 MOA or 1/8 MOA adjustments. Always verify your scope's specifications before making adjustments.
Practical Applications
- Zeroing your rifle scope at specific distances
- Compensating for bullet drop at long ranges
- Adjusting for windage (horizontal corrections)
- Fine-tuning accuracy for competition shooting
- Calculating holdover and holdunder points
- Understanding ballistic trajectories
Frequently Asked Questions
- What does MOA stand for?
- MOA stands for Minute of Angle. It's an angular measurement equal to 1/60th of a degree, commonly used in shooting for scope adjustments and accuracy measurements.
- How many inches is 1 MOA at 100 yards?
- 1 MOA equals approximately 1.047 inches at 100 yards, though it's commonly rounded to 1 inch for practical shooting purposes. This value scales linearly with distance.
- How many clicks is 1 MOA on most scopes?
- Most rifle scopes have 1/4 MOA per click adjustments, meaning 4 clicks equal 1 MOA. However, some scopes use 1/2 MOA or 1/8 MOA increments, so always check your scope's specifications.
- Does MOA scale linearly with distance?
- Yes, MOA scales linearly with distance. If 1 MOA equals ~1 inch at 100 yards, it equals ~2 inches at 200 yards, ~5 inches at 500 yards, and so on.
