Volume - weight calculator for precious metals

At bloomsteins [dot co dot uk] there used to be an online
volume/weight calculator for precious metals where you could find the
weight of x sq. centimeters of sheet of your chosen metal at your
chosen thickness (gauge). This was very handy in figuring out prices,
since I know the dimensions and gauge of sheet I need, but of course,
prices are given by weight. They don’t have this calculator any
more, so does anyone know of such an animal somewhere else?

Hi Janet, Kitco has an app available. Cheers, Karen
