Hi Chunks, Starting copper on outer layer with .0007 is 1/2 oz. copper foil. so if starting copper is .0007 and your Board house will plate an additional .0021 mils of copper. which will give you a finished copper weight of .0028 Mils or (2 oz.) Y

You cannot determine foil thickness from its weight per area, because of the significant variation in the density of electrodeposited [ED] copper. But people don't care. They do it regardless. (oz/ft2)||(mils)||(mm) 1/2||0.7||17.8 1||1.4||35.6 2||2
