The History of the Troy Ounce

The troy ounce, a time-honored weight measurement, has been the gold standard (quite literally) for valuing precious metals for hundreds of years. Its roots can be traced back to the Roman Empire, where traders used the “uncia,” a precursor to both the modern ounce and troy ounce. Later, the troy ounce was refined and adopted in the French city of Troyes, a hub for medieval commerce and trading.

The troy ounce gained prominence when it was officially adopted by the British in the early 1400s as the standard unit of measure for precious metals. Since then, it has been the preferred measurement for commodities like gold, silver, and platinum, especially in markets where accuracy is paramount. Today, the London Bullion Market and the U.S. Mint still rely on the troy ounce to measure and price bullion.

Troy Ounce vs. Imperial Ounce

While both the troy ounce and the more familiar imperial (avoirdupois) ounce are used to measure weight, they are not the same. A troy ounce weighs 31.1035 grams, whereas an imperial ounce is lighter at28.3495 grams. The troy ounce is about 10% heavier than the imperial ounce, which is one reason it is used in high-value commodities where precision is critical.

To put this into perspective: - 1 troy ounce = 31.1035 grams - 1 imperial ounce = 28.3495 grams - 1 troy ounce ≈ 1.0971 imperial ounces

The difference might seem small, but when it comes to trading large quantities of gold or silver, even the slightest variance can result in significant financial discrepancies. For this reason, the troy ounce remains the standard in precious metals trading.

Why Are Precious Metals Quoted in Troy Ounces?

The use of the troy ounce for quoting precious metals like gold and silver is rooted in tradition and precision. Since precious metals are highly valuable, their weight must be measured with exactness. The slightly heavier troy ounce offers the ideal balance between size and weight for this purpose.

Given its long history and reliability, the troy ounce has become deeply embedded in global financial markets. Gold, silver, platinum, and other precious metals are consistently quoted in troy ounces because of this trusted standard. Whether you‘re buying a gold coin, investing in silver bars, or tracking live market prices, the troy ounce ensures clarity and consistency.
