📐 Mathematical Formula & Step-by-Step Substitution
- Determine fineness ratio of 18K gold: 18 / 24 = 0.7500 (or 750.0‰ millesimal fineness).
- Multiply gross weight by fineness: 5 g × 0.7500 = 3.75 grams of fine elemental gold (Au).
- Convert grams to troy ounces (1 oz t = 31.1034768 g): 3.75 / 31.1034768 = 0.1206 troy ounces.
- Convert grams to tolas (1 tola = 11.6638 g): 3.75 / 11.6638 = 0.3215 tolas.
