Calculation of minute of angle or MOA for target optics 1 MOA (one minute of angle or minute of angle) is 1/60th of a degree of angle. At a distance to the target of 100 m, an adjustment of 1 MOA therefore corresponds to an adjustment of 2.9 cm. Example calculation for understanding: The target distance (= radius): 100m or 10,000cm Circumference calculation: 2 x radius x 3.14 (PI) = 628.31m or 62,831.85cm 1 degree then corresponds to 1/360 of the [...]
