Sight depression

I have a doubt about old sights. They calculate the depresion in mils. But, are the mils a universal unit of measure?

Imagine that I have the sight depresion in mils for a F4C, dropping a MK82 at a 30º dive and 450 knots over a target a 0 ft MSL, and a setting for the sight of 121 mils; could I use the same settings in mils for another plane, like a F104 or a F105? ( i guess than the rest of the serttings are the same, because a Mk82 is always a Mk82, and it once dropped it flies always the same pattern)

Thank you!
