Sam Okafor appraises a collection of gold coins for an estate sale. The collection contains 85 troy ounces of gold. Converting: 85 x 0.004896 = 0.4162 stones (about 5.83 pounds or 2.64 kg). He explains to the heirs that the entire gold collection weighs less than half a stone — lighter than a newborn baby — yet at $2,000 per troy ounce, it is worth $170,000.

Practical Applications
Jewelry Collection Insurance
Priya Patel helps a client insure a gold jewelry collection weighing 45 troy ounces. Converting: 45 x 0.004896 = 0.2203 stones (about 3.09 pounds). She explains that the collection weighs barely more than a bag of sugar, yet at current gold prices, it is worth $90,000. The insurer requires weight in both troy ounces and stones on the UK policy document.
Museum Exhibit Planning
Maya Singh volunteers at a museum planning a precious metals exhibit. The centerpiece is a replica gold bar weighing 400 troy ounces. Converting: 400 x 0.004896 = 1.958 stones (about 27.4 pounds or 12.44 kg). The display case must support this weight plus the plexiglass cover. She calculates the total at about 3 stones, well within the pedestal rating of 10 stones.
Personal Investment Tracking
Tom Henderson tracks his gold investment portfolio. He owns 25 troy ounces of gold coins and 10 troy ounces of silver bars. Total precious metals: 35 troy ounces. Converting: 35 x 0.004896 = 0.1714 stones (about 2.4 pounds). He finds it remarkable that his entire investment — worth over $50,000 in gold alone — weighs less than a fifth of a stone, lighter than a large book.
