Calculators to easily help you determine how many clicks to use at what distance for a give value of MOA or MRAD, and the inverse scope click calculation as well.
Scope Click Calculators for inches.
MOA Adjustment Calculator
Result: clicks
MIL Adjustment Calculator
Result: clicks
Instructions:
- You Enter:
- Scope MIL adjustment per click.
- Desired movement of the bullet’s impact in centimeters.
- Target distance in meters.
- Calculation:
- The calculation converts centimeters to meters and uses the standard MIL formula below adjusted for metric units.
- Output:
- The result is displayed in “clicks” needed to adjust the scope.
Formula:
Scope MIL click calculator for metric units (m and cm).

Notes:
1 MOA = 1.047 inch at 100 yards. For most practical purposes you can substitute inches for MOA if your scope specifies MOA at 100 yards. For example: 1/4 MOA at 100 yards = 1/4 inch at 100 yards.
1 MRAD / MIL = 10 centimeters at 100 meters, so 0.1 MRAD is 1 click at 100 meters for MIL rifle scopes. For most practical purposes you can substitute clicks for 0.1 MRAD if your scope specifies the usual 0.1MRAD at 100m. For example: 1 click at 100 meter = 1 cm at 100 meters.

Unsure about bullet drop or what adjustments you’ll need to zero at different distances?
Your best bet is to head to the range and gather some real-world data—empirical data is still the best true data.
Before you go however, you can calculate baseline and sometimes accurate bullet drop data on one of these free ballistics calculators:
