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

Wax Weight × Conversion Factor = Metal Weight

Metalli Wax Factor Metalli Wax Factor Metalli Wax Factor
Kupari 8.34 925 Silver 9.97 14K Yellow 13.05
Nickel Silver 8.69 Pure Silver 10.20 18K Yellow 15.15
Palladium Silver 10.32 8K Gold 10.70 18K Red 15.30
9K Gold 11.01 10K kultaa 11.34 22K Gold 17.63
14K White 12.61 18K White 14.51 24K kultaa 19.00
PT900 18.57 304 Stainless 12.96

Calculation Guide: Target Weight = Original Weight × Conversion Factor
Conversion factors are based on your Excel table’s second matrix (target metal ÷ original metal). For example: 925 Silver to Copper = 1.20

📊 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.

Metal Name Wax Conversion Factor Calculated Density (g/cm³) Standard Density Ref. (g/cm³)
24K kultaa 19.00 19.00 19.32 (Pure Gold)
18K Yellow/Red Gold 15.15 / 15.30 ~15.2 15.2 – 15.6 (Alloy)
14K Yellow Gold 13.05 13.05 ~13.5 (Alloy)
PT950 Platinum (To Be Added) ~21.5 (Alloy)
925 Silver 9.97 9.97 10.4 (92.5% Silver)
Pure Silver 10.20 10.20 10.5 (Pure Silver)
Kupari 8.34 8.34 8.96 (Pure Copper)
304 Stainless Steel 12.96 12.96 7.93 (Standard Value)

Note: The “Wax Conversion Factor” is the value from the “Wax” row in your Excel sheet and can be directly used for “Wax Weight → Metal Weight” calculations. All conversions within this tool are based on this coefficient system.
