The imperial system is a system of measurement that was originally developed in the United Kingdom and is still used in a number of countries around the world, including the United States. In the imperial system, weight is typically measured in pounds (lb) and ounces (oz).

On the other hand, the metric system is a system of measurement that is based on the International System of Units (SI) and is used in most other countries around the world. In the metric system, weight is typically measured in kilograms (kg) and grams (g).

The kilogram is the base unit of mass in the metric system, and it is defined as the mass of a specific reference object, called the International Prototype Kilogram, which is kept at the International Bureau of Weights and Measures in France. The gram is a unit of mass that is equal to 1/1000 of a kilogram.
