Copper foil thickness defined in ounces originated from the days copper foil was used to cover roofs. Thus , 1/2 ounce copper is defined as the "weight of a square foot of copper foil that is .0007 inches thick."

-------------------------------------------------------------------------- --
Can someone throw a basic light on 1 OZ copper, how oz (weight) was
attached
to copper thickness? But 1 oz copper on what surface area.
