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

Metal Wax Factor Metal Wax Factor
Miedź 8.34 14K White Gold 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 22-karatowe złoto 17.63
9K Gold 11.01 PT900 Platinum 18.57
10K Gold 11.34 24K Gold 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.

Gold Price Calculator

Gold Karat Price Calculator

Enter 24K pure gold price per gram to automatically calculate prices for all gold karats

Currency: USD per gram (24K pure gold)
Calculation Formula:
Karat Gold Price = 24K Gold Price × (Karat Number ÷ 24)
Example: 18K Gold Price = 24K Price × (18 ÷ 24) = 24K Price × 0.75
