Not everyone is a math genius and can solve the latter on the fly...

What is interesting is some will find MIL easier to do in their head than MOA and vise versa. Hence the reason I stated what I did. Find the system you like best, make sure the math is doable for you and then go with it. The reality is though that the math on either system is plenty doable with a little practice.
There are 2 formulas for ranging that are both pretty simple and very similar.
MOA target size in inches / MOA reading x 100 = distance to target in yards
MIL target size in inches x 27.8 / MIL reading= distance to target in yards.
One can also use target size in yards x 1000 / MIL reading = distance in yards
No trig needed!
I still think guys get too wrapped up in the math of it all. Unless you are ranging you shouldn't be using any math at all, just measure with the reticle and make the appropriate adjustments. If ranging is needed then there are simple basic math formulas that will get the job done.
