Are you confused about the difference between avoirdupois and metric? You’re not alone. Many people are unsure about which system of measurement to use, and how to convert between the two. In this article, we’ll explore the differences between avoirdupois and metric, and help you understand which one is the proper word to use.
Avoirdupois and metric are two systems of measurement that are commonly used around the world. Avoirdupois is a system of weights and measures that is used primarily in the United States and the United Kingdom. Metric, on the other hand, is a system of measurement that is used in most other countries around the world.
The word avoirdupois comes from the Old French phrase “avoir de pois”, which means “goods of weight”. Avoirdupois is used to measure weight, and is based on the pound. One pound is equal to 16 ounces, and there are 14 pounds in a stone. Avoirdupois is used to measure most things that are sold by weight, such as food and other goods.
Metric, on the other hand, is a system of measurement that is based on the meter, gram, and liter. The word “metric” comes from the Greek word “metron”, which means “measure”. Metric is used to measure length, weight, and volume, and is used in most countries around the world. The metric system is based on multiples of ten, which makes it easy to convert between different units of measurement.
Now that you understand the basics of avoirdupois and metric, let’s dive deeper into the differences between the two systems of measurement.
