In regards to distance, one MOA corresponds to 1.047 inches per 100 yards, so 1 inch at 100 yards and 3 inches at 300 yards.
This can be useful to know when sighting in if you are 2 inches low at 100 yards, you need to move the scope up 2 MOA for 8 increments on a 1/4 MOA increment scope.
MOA can also be used for ranging targets with the right scope, a 12-inch prairie dog will be 12 MOA tall at 100 yards and 6 MOA at 200 yards.
