The Ultimate Guide To Understanding The Difference Between An Ounce And A Troy Ounce

What's the difference between an ounce and a troy ounce?

An ounce is a unit of weight in the avoirdupois system, which is commonly used to measure the weight of everyday objects. A troy ounce, on the other hand, is a unit of weight in the troy system, which is used to measure the weight of precious metals, such as gold, silver, and platinum.

The main difference between an ounce and a troy ounce is the weight. One ounce is equal to 28.35 grams, while one troy ounce is equal to 31.103 grams. This means that a troy ounce is about 10% heavier than an ounce.

The troy system is used to measure the weight of precious metals because it is more precise than the avoirdupois system. This is important because the value of precious metals is based on their weight.

Here is a table that summarizes the key differences between an ounce and a troy ounce:
