What does MOA stand for?

Explanation:
MOA stands for Minute of Angle, a unit of angular measure used in aiming and optics. Since 1 degree equals 60 minutes of angle, 1 MOA is 1/60 of a degree. That small angle translates into a measurable distance on the target: about 1.047 inches at 100 yards, 2.094 inches at 200 yards, and so on. This is why sight adjustments are described in MOA—the amount you move the reticle or sights corresponds to a roughly inch-per-100-yards scale. The other terms aren’t standard in ballistics or optics, so Minute of Angle is the correct understanding.
