The kilogram (kg) is the base unit of mass in the International System of Units (SI). It is internationally recognized as the standard measurement for weight and mass. Unlike pounds, which are often used for everyday weight measurements in some countries, kilograms are standard in scientific, medical, and many international contexts.
