    Your software should calculate your volume. One Cubic Centimeter
    (CC) of water weighs one gram. From there it is just a matter of
    multiplying by the specific gravity of the metal that you wish to
    work with arrive at a final weight. 

	silver = 10
	14k = 13.5
	18k = 15
	platinum = 21

    Specific gravities are listed in numerous references including a few
    catalogs...
