Therefore, it's crucial to always clarify which type of ounce is being referred to, especially when buying or selling.

• Troy Ounce: ~31.1035 grams (used for precious metals)
• Avoirdupois Ounce: ~28.3495 grams (used for general goods)

The Gram: A Metric Unit of Mass

The gram (g) is a unit of mass in the metric system, the internationally recognized system of measurement used in science and most countries around the world. It’s a fundamental unit, with larger and smaller units derived from it (e.g., kilograms, milligrams). Understanding grams is essential for converting from troy ounces and comparing prices across different markets that use metric measurements.

The Role of Grams in Precious Metal Trading

While troy ounces are the traditional unit for quoting prices of gold and silver, many international markets and smaller denominations of precious metals are often priced and sold in grams. For example, gold bars are often available in sizes ranging from 1 gram to 1 kilogram (1000 grams). Being able to convert between grams and troy ounces allows for accurate price comparisons and informed purchasing decisions.
