It's really easy. Just change the options in your ballistics software from MOA to Mils. Actually with MOA knobs you need to print both so you can dial or use the reticle. Here's a cut and paste from something I wrote earlier today to try and explain using the reticle for wind:
With a good reticle one can hold within .1 Mil (1/3 MOA) quite easily. You may miss because you misjudged the wind, but holding the correction accurately is not a problem.
Whether you're using a quick reference drop chart with 10 MPH wind holds printed out like this:
Or a PDA spitting out corrections, you can and should get precise windage corrections the same as you get precise elevation corrections.
For example with the above: You range the target or critter at, any number, it doesn't matter--let's say 732 yds. Your 10 MPH wind correction is .8 Mils. If you estimate the wind value is 5 MPH you hold into it .4 Mils. If you it's 9 MPH you hold into it .7 Mils. If you estimate it's 15 MPH you hold into it 1.2 Mils, etc. If you're using a PDA/Phone it'll spit out whatever correction you need as well, it just takes a bit more time.
Here's an article that may be helpful (just skip over the ranging part):
