Copper weight is ounces per square foot. An archaic form of measure from the
copper coated shingle industry of the Middle Ages(?).

        Subject:        [TN] Oz of Copper v/s surface area

        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.

        I know that 1 OZ copper = 1.4 mils
