In jewelry design and production, we’ve noticed that many clients and industry peers often struggle with metal weight conversions and density-to-price ratios, frequently requiring multiple sources for reference. To simplify this process for everyone—and for ourselves—we’ve created this one-stop tool page. Here, you can quickly convert weights between wax models and metals, view real-time metal reference prices and densities, and streamline your workflow.

WAX TO METAL CONVERSION FACTORS FOR JEWELRY CASTING

Formula: Metal Weight = Wax Weight × Conversion Factor

Μέταλλο	Wax Factor	Μέταλλο	Wax Factor
Χαλκός	8.34	Λευκός χρυσός 14Κ	12.61
Nickel Silver	8.69	14K Yellow Gold	13.05
925 Silver	9.97	18K White Gold	14.51
Pure Silver	10.20	18K Yellow Gold	15.15
Palladium Silver	10.32	18K Red Gold	15.30
8K Gold	10.70	22K Gold	17.63
9K Gold	11.01	PT900 Platinum	18.57
Χρυσό 10Κ	11.34	Χρυσό 24Κ	19.00
304 Stainless Steel	12.96	PT950 Platinum	21.00

Calculation Formula: Target Weight = Original Weight × (Target Wax Factor ÷ Original Wax Factor)
All conversion factors are derived from your complete Excel matrix for accurate casting calculations.

📊 Metal Density Reference Table

The densities below are theoretical approximations derived from this tool’s conversion factors (assuming wax density is 1 g/cm³) and are specific to the calculations on this page. The far-right column provides standard pure metal density for reference.
