Precious Metal Weight Calculator



The value of precious metals often hinges on their weight, whether you’re buying, selling, or crafting jewelry. Accuracy in measuring their weight is vital to ensure fairness and transparency in transactions. This is where the Precious Metal Weight Calculator comes to the rescue.


The Precious Metal Weight Calculator is based on a fundamental formula:

Weight (in grams) = (Density x Volume) / Purity


  • Weight is the weight of the precious metal in grams.
  • Density is the density of the specific precious metal (e.g., 19.32 g/cm³ for gold).
  • Volume is the volume of the metal (e.g., in cubic centimeters).
  • Purity is the purity of the metal, usually expressed as a decimal (e.g., 0.999 for 99.9% pure gold).

How to Use?

Using the Precious Metal Weight Calculator is a straightforward process:

  1. Select the Precious Metal: Begin by specifying the type of precious metal you’re dealing with (e.g., gold, silver, platinum, or palladium).
  2. Enter Values: Input the density of the chosen metal, the volume in cubic centimeters, and the purity as a decimal.
  3. Calculate Weight: Click the “Calculate” button, and the calculator will instantly provide you with the accurate weight of the precious metal in grams.
  4. Use the Result: Armed with the calculated weight, you can now make informed decisions, whether you’re pricing jewelry, estimating the value of a collection, or ensuring the accuracy of a transaction.


Let’s illustrate how to use the Precious Metal Weight Calculator with an example:

Suppose you have a 22-carat gold coin with a volume of 1.5 cubic centimeters and a purity of 0.9167 (91.67%). Using the formula:

Weight (in grams) = (Density x Volume) / Purity

Weight = (19.32 g/cm³ x 1.5 cm³) / 0.9167 ≈ 31.39 grams

So, the gold coin weighs approximately 31.39 grams.


Q1: Is this calculator suitable for all precious metals? A1: Yes, the Precious Metal Weight Calculator can be used for gold, silver, platinum, palladium, and other precious metals. Just ensure you have the correct density value for the metal in question.

Q2: Can this calculator convert between different units of weight? A2: No, this calculator is specifically designed to calculate the weight of precious metals in grams based on density, volume, and purity. To convert between different weight units (e.g., grams to ounces), you may need a separate conversion tool.

Q3: Is the purity value always expressed as a decimal? A3: Yes, when using this calculator, purity should be expressed as a decimal. For example, 99.9% pure gold is expressed as 0.999.


The Precious Metal Weight Calculator is an invaluable tool for anyone working with precious metals. Whether you’re a jeweler, investor, or collector, knowing the exact weight of your gold, silver, platinum, or palladium is essential for pricing, valuation, and accurate transactions. With the straightforward formula and easy-to-use interface, this calculator simplifies what could otherwise be a complex and time-consuming process. In a world where precision and transparency are paramount when dealing with valuable commodities, the Precious Metal Weight Calculator stands as a reliable and indispensable companion.
