Understanding MOA

Minute of Angle (MOA) is a unit of angular measurement. One MOA is 1/60th of a degree, which translates to approximately 1.047 inches at 100 yards. The relationship between MOA and linear distance is proportional to range - as distance increases, the linear measurement of 1 MOA also increases.

Common MOA Applications
  • Scope Adjustments: Many rifle scopes are adjusted in MOA increments (typically 1/4 or 1/8 MOA per click).
  • Group Size: Shooting groups are often measured in MOA to normalize accuracy across different distances.
  • Bullet Drop Compensation: Ballistic calculations use MOA to describe how much a bullet drops at various ranges.
MOA vs. MRAD

While MOA is common in the United States, MRAD (Milliradian) is another angular measurement system used in shooting. 1 MRAD equals approximately 3.6 inches at 100 yards, making it a coarser but easier system for mental math (1 MRAD = 10cm at 100m in metric).

Disclaimer: This calculator provides approximate conversions and should be used for estimation purposes only. Actual bullet impact varies due to environmental factors, ammunition, and firearm characteristics.

Formula:
Inches = MOA × Distance (yards) × 0.01047

What Is the MOA to Inches Calculator?

The MOA to Inches Calculator is a practical unit conversion tool that helps shooters and precision marksmen convert angular measurements into linear distances. Specifically, it calculates how many inches one Minute of Angle (MOA) equals at a given distance.

This calculator functions as a measurement converter by translating the MOA—an angular unit—into inches, which is more intuitive for adjusting scopes or estimating bullet impact points.

Understanding MOA and Its Uses

MOA, or Minute of Angle, is an angular measurement commonly used in shooting, hunting, and ballistics. One MOA equals 1/60th of a degree, which translates to approximately 1.047 inches at 100 yards.

  • Scope Adjustments: Scopes are often adjusted in MOA increments, with each "click" moving the point of impact by a fraction of an inch.
  • Accuracy Measurement: MOA is used to describe group sizes and accuracy at various distances.
  • Ballistic Calculations: Estimating bullet drop or wind drift in linear measurements is easier when you start with MOA.

How to Use the Calculator Effectively

This conversion helper is easy to use and requires just a few steps:

  • Enter the desired MOA value.
  • Input the distance to your target and choose the unit (yards, meters, or feet).
  • Select how many decimal places you want in the result.
  • Choose whether to display a conversion table for quick comparisons.
  • Click "Calculate" to view the result instantly.
  • Click "Reset" to clear all values and start a new conversion.

Why This Tool Is Useful

This value conversion tool helps you make accurate scope adjustments and understand your shooting setup better. Instead of guessing, you can convert measurements with precision and clarity.

Whether you're calculating bullet drop, measuring group size, or adjusting your optics, this unit conversion tool saves time and improves shooting accuracy.

Common Conversion Example

If you want to convert 1.5 MOA at 300 yards into inches:

Inches = 1.5 × 300 × 0.01047 = 4.711 inches

Frequently Asked Questions (FAQ)

  • What does 1 MOA mean at 100 yards?
    Approximately 1.047 inches.
  • Does this tool work with meters and feet?
    Yes. It automatically converts meters and feet into yards for accurate calculations.
  • Can I use it for distances Other than 100 yards?
    Absolutely. The tool scales the calculation based on any distance you input.
  • How accurate is the result?
    Results are approximate but highly reliable for general use. Environmental factors can affect actual bullet performance.
