2 The troy ounce is retained even today as the standard unit of measurement in the precious metals market to ensure purity standards and other common measures remain consistent over time. The troy ounce is often abbreviated to read “t oz” or “oz t.”

What is Ozt on a scale?

Ozt or oz-t or similar marking is for Ounces Troy or Troy Ounces. This measuring system is different than the common ounce and used for buy and selling precious metals. An oz-t is 31.1035 grams, while a common ounce is 28.3495 grams.

Troy Ounces are the measurement used worldwide for precious metals. This includes bullion weights; the commodity market’s price-per-ounce of gold, silver and platinum; the precious metal “spot price”; and the graphs that track the price changes of precious metals over time.

Why do they call it a troy ounce?

The troy ounce is believed to have originated in a French town called Troyes in the Middle Ages. In the early 1500s, the troy ounce was accepted as the official standard of measure for gold and silver in Britain, with the US adopting this measurement method as well in 1828.
