## What is a Troy Ounce

A Troy ounce is a unit of measure that is primarily used in the weighment of precious metals. One Troy ounce is equivalent to 31.1 grams, or about 1.097 standard ounces. The Troy ounce got its name from the French market town of Troyes, where it was first used as a unit of measure for gold and silver in the Middle Ages. The Troy ounce has also been used in other systems of measurement, such as the Apothecaries’ system, but its use is now largely limited to the weighment of precious metals. In addition to being a larger unit of measure than the standard ounce, the Troy ounce is also more precise, making it the preferred choice for jewelers and other professionals who work with small amounts of these materials.

## How to Convert Between Troy Ounces and Other Weights

Troy ounces and other weigh measures can be confusing. Here is a quick guide on how to convert between troy ounces and other weights. When measuring gold, silver, and other precious metals, it is important to use the Troy system of measurement. One troy ounce is equivalent to 31.1 grams, whereas one ounce in the avoirdupois system (the system used for measuring most other objects) is equal to 28.35 grams. This means that there are about 10% more troy ounces in a given weight than there are avoirdupois ounces.

To convert from troy ounces to grams, simply multiply the number of troy ounces by 31.1. For example, 10 troy ounces would be equal to 311 grams. To convert from grams to troy ounces, divide the number of grams by 31.1. So, if you have 311 grams of gold, that would be equal to 10 troy ounces. The troy system is also used when measuring the carat weight of diamonds and other Gemstones. One carat is equal to 200 milligrams or 0.2 grams. So, if you have a 2-carat diamond, that means it weighs 400 milligrams or 0.

## History of the Troy Ounce
