How many troy ounces of fine gold are in 100 grams of 24K gold?

⚡ Instant Calculated Answer

100 grams of 24K gold contains exactly 99.99 grams (3.2148 troy ounces) of pure fine gold, with an intrinsic scrap melt value of approximately $8,679.96 USD at $2,700/oz t.

3.2148 oz t Primary Metric
99.99 g Fine Au Secondary Metric

📐 Mathematical Formula & Step-by-Step Substitution

\[ W_{fine} = W_{gross} \cdot \left(\frac{24}{24}\right) = 100 \cdot 0.9999 = 99.99 \text{ g} = 3.2148 \text{ oz t} \]
Fine_Weight = 100g * (24/24) = 99.99g = 3.2148 oz t
  1. Determine fineness ratio of 24K gold: 24 / 24 = 0.9999 (or 999.9‰ millesimal fineness).
  2. Multiply gross weight by fineness: 100 g × 0.9999 = 99.99 grams of fine elemental gold (Au).
  3. Convert grams to troy ounces (1 oz t = 31.1034768 g): 99.99 / 31.1034768 = 3.2148 troy ounces.
  4. Convert grams to tolas (1 tola = 11.6638 g): 99.99 / 11.6638 = 8.5727 tolas.
