Wax to Metal Calculator for Lost Wax Casting

If you're new to lost wax casting, one of the first things you'll need to work out is how much metal you'll need to transform your wax design into a solid metal piece.

Because wax is significantly lighter than metal, the two weights are very different. Knowing the estimated metal weight before you cast helps you plan costs and avoid expensive surprises.

This free calculator uses specific gravity values to estimate the final metal weight of your wax model. Just enter your wax weight in grams, select your casting metal, and the calculator does the rest.
