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.

| 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 |
| 10 Ayar Altın | 11.34 | 24 Ayar Altın | 19.00 |

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.
| Metal | Wax Conversion Factor | Tool Reference Value | Typical Density (g/cm³) |
|---|---|---|---|
| Bakır | 8.34 | 8.34 | 8.96 (Pure Copper) |
| Nickel Silver | 8.69 | 8.69 | 8.7 – 8.9 (Cu-Ni-Zn Alloy) |
| 925 Silver | 9.97 | 9.97 | 10.4 (92.5% Silver) |
| Pure Silver | 10.20 | 10.20 | 10.5 (Pure Silver) |
| Palladium Silver | 10.32 | 10.32 | ~10.8 (Ag-Pd Alloy) |
| 8K Gold | 10.70 | 10.70 | ~11.5 (33.3% Gold) |
| 9K Gold | 11.01 | 11.01 | ~12.0 (37.5% Gold) |
| 10 Ayar Altın | 11.34 | 11.34 | ~12.5 (41.7% Gold) |
| 304 Stainless Steel | 12.96 | 12.96 | 7.93 (Standard Value) |
| 14K White Gold | 12.61 | 12.61 | ~13.0 (White Alloy) |
| 14K Yellow Gold | 13.05 | 13.05 | ~13.5 (Yellow Alloy) |
| 18K White Gold | 14.51 | 14.51 | ~15.0 (White Alloy) |
| 18K Yellow Gold | 15.15 | 15.15 | 15.2 – 15.6 (Yellow Alloy) |
| 18K Red Gold | 15.30 | 15.30 | 15.2 – 15.6 (Red Alloy) |
| 22K Gold | 17.63 | 17.63 | ~17.8 (91.7% Gold) |
| PT900 Platinum | 18.57 | 18.57 | ~20.5 (90% Platinum) |
| 24 Ayar Altın | 19.00 | 19.00 | 19.32 (Pure Gold) |
| PT950 Platinum | 21.00 | 21.00 | ~21.5 (95% Platinum) |
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.
