Old school vs mils

[Kentucky]

I am trying hard to figure mil's rather than inches. After zeroing my 223 in at 250 yrds I was shooting a 1.5 in group. NOW, what would that be in mils and how in the heck did you come up with it? If I figure 1/4 in at 100 yards that would be 1mil? If that is true then 1click in theory would be 1/2 mil at 200 yards. But now if I am on base with this so far 1click at 100 would not be any where close at 400. I am so confused.

And the last thing you need to be is confused when all your fingers are acting like thumbs anyway when your trying to get ready to shoot at a trophy animal.
If it aint broke why fix it?

Don't use inches. Use Minutes of angle. 1.5 inches at 250 yds= how many moa?
1 mill= 3.6" at 100 yds
Here are 2 solutions take your inches 1.5 divide that by yards to target/100 in your case 250/100=2.5 1.5/2.5=.6 moa To get mils from this number divide by 3.6
.6/3.6=.16666...
3.438MOA=1mill
If you have 1/4 moa turrets and you need to correct to a mildot scope. For 1 mill adjustment you need 3.438 moa or 14.4 clicks per mill.
