How it works
- Grams = × Conversion factor
- Troy ounces = Grams ÷ 31.1034768
- Estimated metal value = Troy ounces × Reference per troy ounce
- Worked example: For pure gold weighing 31.1034768 g, the weight is exactly one troy ounce. At a hypothetical USD 2,000 per troy ounce, the estimated metal value is USD 2,000. This is not a current quote or a dealer offer.
- 31.1034768 ÷ 31.1034768 = 1; 1 × 2,000 = 2,000 USD.

Assumptions and limitations
One troy ounce is exactly 31.1034768 g. Enter pure-metal weight; this tool does not infer alloy purity. Frankfurter XAU, XAG, XPT and XPD reference units represent troy ounces, not ordinary ounces. The dated reference is an estimate, not a live bullion quote. Dealer premiums, fabrication, taxes and collectible value are excluded.
