Minute of Angle is 1/60th of a degree. See Figure 9.2-2. Figure 9.2-2 If we spread two laser pointers apart 1 MOA (1/60th of a degree), the dots would be about 1 inch apart at 100 yards, about 2 inches apart at 200 yards, about 3 inches apart at the 300 yards and so on. Simply stated, this means that 1 Minute of Angle is about 1 inch per 100 yards. I say “about” 1 inch since 1 MOA is truly 1.047 inches per 100 yards, but using 1 inch per 100 yards is close enough for our purposes.
