I was looking for a quick way to calculate target width in mils when the target size in inches and range in yards is known. I didn't find anything but made a spreadsheet that is easy to use. The equation is:
(Target Width in Inches / Range to Target in Yards ) X 27.77 = Target width in Mils
Here is a dropbox link for the spreadsheet:
(Target Width in Inches / Range to Target in Yards ) X 27.77 = Target width in Mils
