Understanding Mil to MOA Conversion
What Mil Means
A mil is an angular unit. It is often used in scopes, optics, maps, and targeting systems. One mil represents one thousandth of a radian. It is useful because it scales with distance. A small angle creates a larger shift as distance grows.
What MOA Means
MOA means minute of angle. It divides one degree into sixty equal parts. Shooters often use MOA because many scope turrets adjust in MOA clicks. One MOA is about 1.047 inches at 100 yards. This makes it practical for field calculations.
Why Convert Mil to MOA
Many users compare optic systems. Some scopes use mil adjustments. Others use MOA adjustments. A conversion tool helps users move between both systems. It also reduces guesswork. Clear conversions support better notes, charts, and training records.
True MOA and Shooter MOA
True MOA uses the accurate angular value. Shooter MOA is a rounded field value. The difference is very small for common use. Still, advanced users may need both. This calculator displays both values so you can compare them quickly.
Range and Linear Shift
Angular values grow with range. One MOA at 100 yards is about 1.047 inches. At 200 yards, it doubles. At 300 yards, it triples. The same idea works with centimeters at meters. This tool estimates that linear shift for your selected range.
Practical Use
Use this calculator for optic adjustment planning, ballistic worksheets, angular lessons, and range logs. It is not a replacement for safe training, verified ballistic data, or local rules. Always confirm adjustments carefully before applying them in real use.
FAQs
1. What is the mil to MOA conversion?
One mil equals about 3.43774677 true MOA. Many field users round it to 3.438 MOA for simpler calculations.
2. Is shooter MOA different from true MOA?
Yes. True MOA is mathematically exact. Shooter MOA uses a rounded value, usually close enough for many field uses.
3. Why does the calculator show inches?
MOA is angular. Inches show the estimated linear shift at 100 yards or another selected range.
4. Can I use meters instead of yards?
Yes. Select meters as the range unit. The calculator then estimates shift in centimeters.
5. What is 1 mil in MOA?
One mil equals about 3.4377 true MOA. Rounded shooter value is commonly shown as 3.438 MOA.
6. What is 0.1 mil in MOA?
Zero point one mil equals about 0.3438 MOA. This is a common small adjustment step.
7. Can I download the result?
Yes. Use the CSV button for spreadsheet data. Use the PDF button for a simple report.
8. Is this calculator for learning?
Yes. It helps explain angular conversion, range scaling, and optic unit comparison in a simple format.
