How many troy ounces of fine gold are in 25 grams of 9K gold?

⚡ Instant Calculated Answer

25 grams of 9K gold contains exactly 9.375 grams (0.3014 troy ounces) of pure fine gold, with an intrinsic scrap melt value of approximately $813.78 USD at $2,700/oz t.

0.3014 oz t Primary Metric
9.375 g Fine Au Secondary Metric

📐 Mathematical Formula & Step-by-Step Substitution

\[ W_{fine} = W_{gross} \cdot \left(\frac{9}{24}\right) = 25 \cdot 0.3750 = 9.375 \text{ g} = 0.3014 \text{ oz t} \]
Fine_Weight = 25g * (9/24) = 9.375g = 0.3014 oz t
  1. Determine fineness ratio of 9K gold: 9 / 24 = 0.3750 (or 375.0‰ millesimal fineness).
  2. Multiply gross weight by fineness: 25 g × 0.3750 = 9.375 grams of fine elemental gold (Au).
  3. Convert grams to troy ounces (1 oz t = 31.1034768 g): 9.375 / 31.1034768 = 0.3014 troy ounces.
  4. Convert grams to tolas (1 tola = 11.6638 g): 9.375 / 11.6638 = 0.8038 tolas.
