📐 Mathematical Formula & Step-by-Step Substitution
- Determine fineness ratio of 9K gold: 9 / 24 = 0.3750 (or 375.0‰ millesimal fineness).
- Multiply gross weight by fineness: 20 g × 0.3750 = 7.5 grams of fine elemental gold (Au).
- Convert grams to troy ounces (1 oz t = 31.1034768 g): 7.5 / 31.1034768 = 0.2411 troy ounces.
- Convert grams to tolas (1 tola = 11.6638 g): 7.5 / 11.6638 = 0.643 tolas.
