Hatch distance

[saryyev_m781518]

Hi, I am trying to get the right distance on a hatch pattern. Attached is the file where its shown as an example. I was trying to edit that scale multiplication it gets somewhere approximate, but
if someone knows math to make it sharp 8" please let me know. In the file every pattern is 5 feet, and on scale factor its shown as 10.00000, I have no idea what this number means, I need to convert that to be precisely 8 inches.
If someone knows please share.

At a guess you should change the pattern scale at 10*8/(5*12) = 1.666666667

Edit: Of course the right number is 1.333333333. So much for mental arithmetic,
