Precious Metals and the Troy Ounce

In my 30 plus years of buying precious metals, I have found that many people do not realize that Gold, Silver, Platinum and Palladium are weighed in Troy Ounces. Most everything else (items at the grocery store, for example) is weighed in Avoirdupois Ounces.

An example that I frequently use is that Ounce of gold weighs 31.1 grams and an Ounce of cheese weighs 28.3 grams.

What Is a Troy Ounce?

A troy ounce is a unit of measure used for weighing precious metals, (such as gold, silver, platinum, and palladium), that dates to the Middle Ages. Originally used in Troyes, France, one troy ounce is equal to 31.1035 gram.

A standard ounce, used to weigh other items such as sugar and grain, is slightly less at 28.35 grams.

Troy ounce is the standard unit of measurement in precious metals market ensuring purity standards and other common measures remain consistent over time. The troy ounce is often abbreviated to read "t oz" or "oz t".
