Understanding Troy Ounces and Pounds: A Comprehensive Guide
The confusion between troy ounces and avoirdupois ounces is a common one, mainly because they are used for different purposes. This guide will help clarify the differences between these units and their practical implications.
Introduction to Troy and Avoirdupois Systems
In the context of weight and measurement, two primary systems are used: the troy system and the avoirdupois system. Each has its own definitions and uses for different types of materials.
The Troy System
The troy system uses troy ounces and troy pounds, which are specifically used for measuring precious metals like gold, silver, and platinum. One troy pound contains 12 troy ounces, while one troy ounce is closer to 10 percent more than a standard ounce (avoirdupois). This system is primarily used in the precious metals trading industry.
The Avoirdupois System
In contrast, the avoirdupois system is more common in everyday American measuring. One avoirdupois pound contains 16 avoirdupois ounces. This system is widely used for measuring common goods like food, clothing, and other commodities.
