Errr.. Huh? Yes I really am that dumb when it comes to this sort of thing. 

Let me try again:

If I have copper thickness in mills, what mathematical formula yields
oz/ft2?

If I have copper thickness in oz/ft2, what mathematical formula yields
mills?

K. Give me a set of formula and I'll add another option.


Thanks for trying to help.
