There are essentially three different ways to correct for trajectory or wind when shooting at long range; mil, MOA and the inch.
Mil, MOA or inches?
1 MOA = 1.0472" at 100 yds
1 mil = 3.6" at 100 yds
1 mil = 3.4377 MOA (at any distance, both are angular measurements)
3.5 mils = 12.03 MOA ; let's round it up to 12 MOA = 48 clicks
1 click = 1/4 or 1/8 MOA (depends on the scope)
