About Stone (st)
A British imperial unit of mass equal to 14 pounds (about 6.35 kilograms). The stone is still the everyday unit for personal body weight in the United Kingdom and Ireland — where people say "I weigh 12 stone" rather than 168 pounds or 76 kilograms. Officially abolished from UK commerce in 1985, the stone nonetheless remains cultural shorthand on British bathroom scales, medical charts, and casual conversation about weight. Equine and livestock weights in Britain are also still sometimes quoted in stones.
About Kilogram (kg)
The base unit of mass in the International System of Units (SI), defined since 2019 by fixing the numerical value of the Planck constant. Kilograms are the global standard for scientific measurement, shipping weights, food packaging in most of the world, and body weight outside the United States. One kilogram of water occupies almost exactly one liter, a design feature of the metric system that makes unit conversions across mass, volume, and density remarkably clean.
