One pound (weight) is a unit of mass commonly used in the United States and other countries that follow the imperial system. It is equivalent to 16 ounces and is defined as exactly 0.45359237 kilograms in the metric system. The pound is often used to measure the weight of food, packages, and other everyday items. In various contexts, the pound can also refer to the British Pound Sterling, which is a unit of currency. However, in terms of weight, it is primarily associated with physical mass rather than monetary value. Understanding pounds is essential for cooking, shipping, and other practical applications.
