The metal weight calculator is very easy to use on your desktop computer, your smartphone or iphone. Need a hand showing how to add the icon to your smart phone.
The densities used to calculate metal weights based on dimesion are taken from reliable sources such as MatWeb and Metal Suppliers Online.
They have been crosschecked against densities reported by producing mills. If there has been a slight discrepancy between values, they have been averaged to come up with the most accurate measure possible. This may be the most extensive and reliable metal weight calculation tool on the web. However, plus and minus tolerances will slightly alter weight of finished metals.
