I prefer to convert the target width or height (whatever's being measured) to distance units first (yards or meters), e.g. 18" = .5 yards. Multiply that times 1000 and you have the distance at 1 mil, e.g. 500 yards. Then divide by mils read, 500 / .8 mils = 625.
Metric users have it a bit easier, since all units are decimal, e.g. 54 cm = .54 meters. With yards and inches, I found it helped to remember that every 4 inches is ~.11 yards:
4 0.11
8 0.22
12 0.33
16 0.44
20 0.56
24 0.67
28 0.78
32 0.89
36 1.00
Got a target size like 19"? Just go with 20, especially if the mils read is greater than 1. Frankly, if you're dealing with a target less than 18" and are reading less than .75 mils, you'd better be really good. The farther out you shoot, the harder it is to range and ballistics are increasingly not in your favor. If you're off by 25 yards at 750 yards that's probably a miss.
