It has historical roots dating back to ancient Rome and has evolved over centuries into the modern avoirdupois pound. The pound is often used to measure body weight, food quantities, and other everyday items.

The Kilogram (kg)

The kilogram is the base unit of mass in the International System of Units (SI). It is used worldwide for scientific, commercial, and everyday measurements. The kilogram was originally defined in 1795 as the mass of one liter of water but has since been redefined based on fundamental physical constants.

Conversion Factor Between Pounds and Kilograms
