Differences Between Troy Ounces and Ounces

In the realm of measurements, ounces and troy ounces are two distinct units often encountered in various industries, particularly when dealing with precious metals and gemstones. Understanding the difference between these two units is crucial for accurate weighing and proper quantification of materials.

What is an Ounce?

An ounce (oz) is a unit of mass or weight in the avoirdupois system, which is commonly used in everyday applications. It is defined as 1/16 of a pound or 28.3495 grams. Ounces are primarily employed in measuring the weight of various substances, including food, beverages, and consumer goods.

What is a Troy Ounce?

A troy ounce (t oz) is a unit of mass or weight specific to the troy weight system, primarily used in the precious metals and gemstones industries. It is defined as 1/12 of a troy pound or 31.1034768 grams. The troy weight system originated in the city of Troyes, France, in the Middle Ages as a standardized method for weighing precious materials.

Key Differences between Troy Ounces and Ounces
