MOA to Inches Calculator
To simply convert Minute of Angle (MOA) to inches, Enter the number of MOA adjustments (e.g., 2.5 MOA).
Enter Distance: to the target in yards (e.g., 200 yards)
The calculator computes linear measurements and click adjustments
This MOA to inches calculator uses the standard formula of 1 MOA = 1.047 inches at 100 yards to calculate bullet drop and scope adjustments.

MOA Calculation Formula
The standard equation for converting MOA to inches is:
Inches = MOA × Distance (yards) × 1.047 ÷ 100Where:
- MOA = The number of MOA adjustments.
- Distance (yards) = Distance to the target in yards.
- 1.047 = Conversion factor for 1 MOA at 100 yards (1 MOA ≈ 1.047 inches at 100 yards).
Inches = (MOA × Distance) / 100Where:
- MOA is the angular measurement
- Distance is in yards
- Result is in inches
For metric calculations:
Centimeters = Inches × 2.54
Millimeters = Centimeters × 10- ¼ MOA scopes: 4 clicks per MOA
- ½ MOA scopes: 2 clicks per MOA
- 1 MOA scopes: 1 click per MOA
Example calculation for 3 MOA at 200 yards:
Inches = (3 × 200) / 100 = 6.282 inches
¼ MOA clicks = 3 × 4 = 12 clicksHow to Convert MOA to Inches
- Determine the MOA value you’re working with, Know your target distance in yards, Remember the conversion factor (1.047)
- Apply the formula: Multiply all three numbers together and Divide by 100
- Interpret the results: The final number represents the linear measurement in inches
Converting 3 MOA at 250 yards
Inches = (3 × 250 × 1.047) ÷ 100
Inches = 7.8525 inches
- 4 MOA at 100 yards: (4 × 100 × 1.047) ÷ 100 = 4.188 inches
- 2.5 MOA at 300 yards: (2.5 × 300 × 1.047) ÷ 100 = 7.8525 inches
- 1.5 MOA at 500 yards: (1.5 × 500 × 1.047) ÷ 100 = 7.8525 inches
- 3.5 MOA at 150 yards: (3.5 × 150 × 1.047) ÷ 100 = 5.49675 inches
- 1 MOA at 400 yards: (1 × 400 × 1.047) ÷ 100 = 4.188 inches
What is MOA?
MOA (Minute of Angle) is an angular measurement equal to 1/60th of one degree. It’s widely used in shooting sports and rifle scopes because it provides precise adjustment values. At 100 yards, 1 MOA equals approximately 1.047 inches, though it’s often rounded to 1 inch for practical purposes.
The linear size of 1 MOA increases proportionally with distance, making it an effective system for long-range shooting and scope adjustments. Most rifle scopes use either ¼ MOA or ½ MOA click values for precise targeting.
