2.9472 oz t Primary Metric
91.667 g Fine Au Secondary Metric

📐 Mathematical Formula & Step-by-Step Substitution

\[ W_{fine} = W_{gross} \cdot \left(\frac{22}{24}\right) = 100 \cdot 0.9167 = 91.667 \text{ g} = 2.9472 \text{ oz t} \]
Fine_Weight = 100g * (22/24) = 91.667g = 2.9472 oz t
  1. Determine fineness ratio of 22K gold: 22 / 24 = 0.9167 (or 916.7‰ millesimal fineness).
  2. Multiply gross weight by fineness: 100 g × 0.9167 = 91.667 grams of fine elemental gold (Au).
  3. Convert grams to troy ounces (1 oz t = 31.1034768 g): 91.667 / 31.1034768 = 2.9472 troy ounces.
  4. Convert grams to tolas (1 tola = 11.6638 g): 91.667 / 11.6638 = 7.8591 tolas.
