How Do You Convert Pounds to Troy Ounces?
Multiply pounds by 14.5833 to get troy ounces. The formula is: Troy Ounces = Pounds x 14.5833. Since 1 pound = 453.592 grams and 1 troy ounce = 31.1035 grams, the ratio is 453.592 / 31.1035.
Sam Okafor calculates the gold content in a large antique clock. The gilded bronze case weighs 35 pounds total, and the gold plating accounts for about 0.15 pounds. Converting: 0.15 x 14.5833 = 2.187 troy ounces of gold. At $2,100/ozt, the gold content alone is worth about $4,593, which he adds to the antique value assessment.

Practical Applications
Scrap Gold Buying
Marco Ferreira brings a bag of broken gold jewelry to a buyer. The total weight is 0.8 pounds = 11.67 troy ounces of mixed karat gold. After acid testing: 0.3 lb is 18K (3.28 ozt pure gold), 0.4 lb is 14K (3.40 ozt pure), and 0.1 lb is 10K (0.608 ozt pure). Total pure gold: 7.29 ozt x $2,100 = $15,309 melt value. The buyer offers 85% = $13,013.
Coin Collection Valuation
Tom Brewer inventories his silver coin collection. He has 3.2 pounds of pre-1965 US silver coins. Converting: 3.2 x 14.5833 = 46.67 troy ounces total weight. Pre-1965 US coins are 90% silver, so silver content = 42.0 ozt. At $28/ozt, the silver value is $1,176. Some coins have numismatic premiums above melt, which he researches individually.
Jewelry Manufacturing
Leah Novak orders gold casting grain for her jewelry workshop. She buys 0.25 pounds = 3.646 troy ounces of 14K casting grain. At $1,225/ozt for 14K (58.3% of $2,100 spot), the material costs $4,466. She expects to produce about 30 small pendants, with material cost of roughly $149 per piece before labor, gems, and overhead.
