How to Calculate
To calculate gold weight, measure your gold object's dimensions (length, width, height) and determine its shape. The calculator uses the formula **Weight = Volume × Density**, where gold's density is 19.32 g/cm³. First, calculate the volume based on the shape (for a rectangular bar: length × width × height), then multiply by gold's density. Adjust for purity if your gold is less than 24K — for example, 18K gold is 75% pure, so multiply the result by 0.75.
Formula & Method
Weight (g) = Volume (cm³) × 19.32 g/cm³ × Purity Factor
For rectangular bars: Volume = Length × Width × Height For cylinders: Volume = π × r² × Height For spheres: Volume = (4/3) × π × r³
Purity factors: 24K = 1.0, 22K = 0.917, 18K = 0.75, 14K = 0.583, 10K = 0.417
