kilograms (kg)

The kilogram (kg) is the base unit of mass in the International System of Units (SI). Established in 1795 as the mass of one liter of water at the freezing point, it has been the world's standard for over two centuries. Until 2019, it was defined by a physical platinum-iridium cylinder locked in a vault in Paris (Le Grand K). Today, it is defined by the Planck constant, a fundamental constant of quantum physics, ensuring it remains stable and precise forever.

The pound (lb) traces its roots to the Roman 'libra', which is why its abbreviation is 'lb'. The modern 'avoirdupois pound' was standardized in 1959 to be exactly 0.45359237 kilograms, creating a bridge between the imperial and metric worlds. While the UK has officially adopted metric, the pound remains the cultural standard for body weight there (often via 'stones') and is the official unit of weight in the United States.
