I made this MIL to MOA conversion scale a while back and keep a copy saved on my phone.
Any time we need to convert between MILs and MOA we open it, zoom in and swipe to where we need to convert. It works really well.
I thought I'd share it with you guys if you would like to download the image and keep it on your phone.
Someone should make a keychain measuring tape like this, but longer with more detail.
