The Inches to MOA Calculator is designed to convert the group size from inches to Minute of Angle (MOA), which is a common unit of measurement used in long-range shooting. MOA is a critical metric for precision shooters and is essential for understanding shot group sizes at various distances.
Understanding Minute of Angle (MOA)
Minute of Angle (MOA) is a unit used to measure angular size, commonly used in shooting sports. One MOA is equivalent to 1/60th of a degree. At 100 yards, 1 MOA roughly equals 1.047 inches. This means that if a shot group measures 1 MOA at 100 yards, it would be approximately 1.047 inches in diameter. MOA is essential for adjusting rifle scopes and for accurately measuring shot groups.
How to Use the Inches to MOA Calculator
To use the Inches to MOA Calculator:
- Enter the distance to the target in yards.
- Input the group size in inches.
- Click on the “Convert” button to get the group size in MOA.
- If needed, click on the “Reset” button to clear the fields.
The conversion formula used by this calculator is:
MOA = (Group Size in Inches / Distance in Yards) * 100 * 4.17
Example Calculation
For instance, if you have a group size of 2 inches at a distance of 300 yards, the MOA calculation would be:
MOA = (2 / 300) * 100 * 4.17 = 2.78 MOA
Why MOA Matters
Understanding MOA is crucial for precision shooting as it helps shooters make necessary adjustments to their scopes to account for bullet drop and wind drift. By converting group sizes into MOA, shooters can better gauge their accuracy and make adjustments to improve their shooting performance.
