About the kilogram and the stone

The kilogram

The kilogram (kg) is the SI base unit of mass. Since the 2019 redefinition it is defined by fixing the Planck constant to exactly 6.62607015 × 10⁻³⁴ J·s, replacing the old International Prototype Kilogram artifact. In everyday use, the kilogram is the global standard for body weight, groceries, and engineering specifications.

The stone

The stone (st) equals exactly 14 pounds (about 6.35 kg). It is still widely used in the United Kingdom and Ireland to state body weight, even though it is no longer legal for trade. The stone was originally a real stone used by merchants as a counterweight on balances; its weight varied by region and trade until standardized in the late 19th century.
