Example: Convert wax to metal

Wax model weight x factor of metal wanted = weight of metal wanted

1 DWT. (wax) x 10.40 (sterling factor) = 10.40 DWT. sterling

Example: Finding weight of an object in a different metal than it is now.

Model weight in metal x factor of metal wanted = weight of metal wanted

Sterling Ring 10 DWT. x 1.25 (14K factor) = 12.50 DWT. 14K
