Inches and Mrad relationship

[Kingfish]

Most targets come in 1" grid markings. My scopes are Mrad. I'm looking for an app to put on my phone to do the conversions. As an example, if I am shooting 10 inches high at 500 yds, I need to be able to convert that to x number of mils to make my scope adjustment. Right now I am using ChatGP and asking it for the solution, which works quite well, but is obviously not a reliable solution in all situations. I am sure there is a formula to do this conversion that wouldn't require any electronic device. I imagine there may well be a chart of some sort out there that would show these corrections. If you have one please share it or a link to it.

It’s all based on 10.
1/10mil @ 100 = 0.36”
1 mil @ 100 = 3.6”
1/10 mil @ 1000 = 3.6”
1 mil @ 1000 = 36”

So 1/10 mil @ 500 is one half of 3.6” or 1.8”.
1/2 mil or 5/10 mil @ 500 will be 9”. Dial 1/2 mil or 6/10 mil and you should be good.
