Formula and methodology
Formula: Gross troy ounces = entered weight × unit conversion × quantity; fine troy ounces = gross troy ounces × purity / 100; melt value = fine troy ounces × gold price per troy ounce; account value = quote value × quote-to-account rate.
Gold is commonly quoted per troy ounce while jewellery and bars may be weighed in grams or kilograms. This calculator makes the unit conversion and purity adjustment visible, producing a metal-content estimate rather than a retail appraisal.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Gold price per troy ounce — quote currency / troy oz; minimum 1.0E-8; maximum 1000000000
- Gold weight — selected weight unit; minimum 1.0E-8; maximum 1000000000
- Weight unit — 3 choices
- Purity — %; minimum 1.0E-6; maximum 100
- Number of items — items; minimum 1.0E-6; maximum 1000000000
- Quote currency to account currency — account / quote; minimum 1.0E-10; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Gold price per troy ounce | 2300 |
| Gold weight | 31.1034768 |
| Weight unit | gram |
| Purity | 99.9 |
| Number of items | 1 |
| Quote currency to account currency | 1 |
31.1034768 grams equal 1 gross troy ounce; at 99.9% purity the fine content is 0.999 troy ounce and the estimated melt value is 2,297.70 quote and account-currency units.
Assumptions and limits
- The entered price is quoted per troy ounce of fine gold.
- One troy ounce equals 31.1034768 grams in this conversion.
- Purity percentage describes the fraction of the gross weight treated as gold content.
- All items have the same entered weight and purity.
- The quote-to-account rate is account currency for one quote-currency unit.
- The calculation estimates metal content value, not an offer to buy.
- Dealer premium, fabrication, assay, taxes, storage, and selling spread are excluded.
- The displayed price may differ from a local dealer’s realizable bid.
- Coinage, stones, workmanship, and collectible value are outside the model.
