Jewelry Metal Weight convertion

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

Металл	Wax Factor	Металл	Wax Factor
Медь	8.34	Белое золото 14 карат	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	Золото 22 карата	17.63
9K Gold	11.01	PT900 Platinum	18.57
Золото 10 карат	11.34	24-каратное золото	19.00
304 Stainless Steel	12.96	PT950 Platinum	21.00
Палладий	14.32

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.
