When it comes to weight measurement, different units of measurement are used in different parts of the world. Pounds and ounces are commonly used to measure weight in the United States, particularly when measuring food ingredients, packages, or even human weight.

## What is a pound?

A pound is a weight unit that is commonly used in the United States, the United Kingdom, and other countries that use the imperial measurement system. It is represented by the abbreviation “lb” or “lbs” and is equivalent to 16 ounces. One pound is about the weight of a medium apple or a small bag of sugar. Historically, the pound was defined as 7,000 grains based on the weight of a grain of barley. It is now precisely 0.45359237 kilogrammes.

It is abbreviated as “oz” and equals 1/16 pound (0.0625 pounds). One ounce is roughly equivalent to one slice of bread or one small piece of chocolate. The ounce, like the pound, has a long history and was based on the weight of a single grain of barley at one time. It is now precisely 0.0283495231 kilogrammes.
