[QUOTE="redleg1013, post: 1602905, member: 49994"] Multiply or divide 1.047 as applicable. 1 true MOA = 1.047" Taken from Snipers Hide: "Nothing worse than dialing up then having to mathematically figure the error. For ranging out to 1k you'll note there is only .47" difference in moa vs. iphy/smoa. But when you start dialing it, that 5% difference really adds up. To the tune of 16-20" @ 1000 yds., depending on what round you are shooting. So if your calculations are in mils and you dial up in mils with no error, just follow the numbers and hit it. Same with iphy and same with moa. The only issue I can see is with iphy, you don't start with a relatively rounded number as far as angular measurement. That's if you have to start completely from the beginning. In moa it's 1/60 => sin => x 3600(inches in 100 yds) But, if shooting metric you then need to convert metric to yds. And that is a pain in itself all over again (military maps are metric...sometimes we have to range that way)." [/QUOTE]
