Basics of Ounces and Pounds
The Ounce (oz)
The ounce is a unit of weight commonly used in the United States customary and imperial systems. It is primarily used for measuring small quantities of mass or weight, such as food ingredients, precious metals, or small packages. There are different types of ounces, but the most widely used in weight measurement is the avoirdupois ounce.
The Pound (lbs)
The pound is a larger unit of weight measurement, also part of the avoirdupois system. It is used extensively in the United States and other countries for measuring body weight, produce, and other commodities. The abbreviation for pound is "lb," which originates from the Latin word "libra."
The Relationship Between Ounces and Pounds
