What is Stone?
Stone (st) is a unit of weight. The stone is a British unit of mass equal to exactly 6.35029 kilograms. It is primarily used for measuring body weight in the UK and Ireland. The stone is recognized by British Imperial and US customary systems but is not part of the SI [nist-sp-811]. The stone originated in England around the 14th century as a trading weight, varying by region and commodity. It was standardized to 14 pounds (6.35029 kg) in the 19th century to unify weights in commerce [nist-sp-811]. The stone remains in common use for body weight in the UK, Ireland, and some Commonwealth countries. It is not used in scientific or medical contexts, which prefer kilograms [nist-sp-811].
What is Kilograms?
Kilograms (kg) is a unit of weight. The kilogram is the SI base unit of mass, defined by the Planck constant fixed at exactly 6.62607015×10⁻³⁴ joule seconds. It represents the mass equal to that of the International Prototype Kilogram and is the only SI base unit still defined by a physical constant rather than a physical artifact [bipm-si-brochure]. The kilogram originated in 1795 as the mass of one liter of water at 4 °C. It was redefined in 2019 using the Planck constant to ensure long-term stability and universality, replacing the physical prototype standard maintained by the BIPM [bipm-si-brochure]. Kilograms are the primary unit of mass in nearly all countries, used in science, commerce, and industry. The SI system, adopted globally, mandates kilogram usage in trade, health, and manufacturing sectors [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: stones, stne, ston, stonne, kilo, kilogramme, kilogramm, kilograms. All of these refer to the Stone to Kilograms conversion.
