Stone (st)
Definition
A stone (st) is an imperial unit of mass equal to 14 pounds or approximately 6.35029 kilograms.
History
The stone has been used as a weight measure in England and Ireland since at least the 14th century. Different commodities historically used different stone weights; the 14-pound stone was standardized in 1835 by the British Weights and Measures Act.
Current use
Stones are primarily used in the United Kingdom and Ireland to express body weight (e.g., '11 stone 4 pounds'). They are not used in the United States or most other countries.
Kilograms (kg)
Definition
A kilogram (kg) is the SI base unit of mass, equal to 1,000 grams. Since 2019, it is defined by the Planck constant rather than a physical artifact.
History
The kilogram was established in 1795 during the French Revolution as the mass of one liter of water. From 1889 to 2019, it was defined by the International Prototype of the Kilogram (a platinum-iridium cylinder in Paris). The 2019 redefinition linked it to the Planck constant for improved precision.
Current use
Kilograms are the universal standard for body weight, grocery products, luggage allowances, industrial materials, and scientific measurements. It is the base unit of mass in all scientific and most commercial contexts worldwide.
