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.
Jewelry Metal Weight Converter
UNIT CONVERSION
VOLUME CASTING CONVERSION
WAX TO METAL CONVERSION
Wax Weight × Conversion Factor = Metal Weight
| Metall | Wax Factor | Metall | Wax Factor | Metall | Wax Factor |
|---|---|---|---|---|---|
| Kobber | 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 gull | 11.34 | 22K gull | 17.63 |
| 14K White | 12.61 | 18K White | 14.51 | 24K gull | 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 gull | 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) |
| Kobber | 8.34 | 8.34 | 8.96 (Pure Copper) |
| 304 Stainless Steel | 12.96 | 12.96 | 7.93 (Standard Value) |
Merk: 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.
