📐 Mathematical Formula & Step-by-Step Substitution
- Determine fineness ratio of 21K gold: 21 / 24 = 0.8750 (or 875.0‰ millesimal fineness).
- Multiply gross weight by fineness: 250 g × 0.8750 = 218.75 grams of fine elemental gold (Au).
- Convert grams to troy ounces (1 oz t = 31.1034768 g): 218.75 / 31.1034768 = 7.033 troy ounces.
- Convert grams to tolas (1 tola = 11.6638 g): 218.75 / 11.6638 = 18.7546 tolas.
