The Basics of Kilograms and Pounds
What Is a Kilogram?
A kilogram (kg) is the base unit of mass in the International System of Units (SI). It is widely used worldwide for weighing objects, measuring body weight, and in scientific contexts. The kilogram was originally defined in 1795 as the mass of one liter of water, but since 2019, it has been defined based on fundamental constants of nature, specifically the Planck constant.
What Is a Pound?
The pound (lb) is a unit of weight commonly used in the United States and other countries that follow the imperial or customary measurement systems. Unlike the kilogram, which is a measure of mass, the pound is traditionally considered a measure of force, but in everyday use, it is treated as a unit of mass.
