What does lb stand for in terms of weight?

The abbreviation "lb" stands for pound, which is a unit of weight commonly used in the United States and some other countries. The term originates from the Latin word "libra," referring to the Roman pound. One pound is equivalent to 16 ounces and is widely used for measuring body weight, food products, and other materials.

In contrast, a kilogram is a metric unit of mass, pints and gallons are units of volume, which are not relevant when discussing weight. Understanding the correct meaning of "lb" is crucial for tasks that involve weight measurement, such as dosing medication or understanding nutritional information.
