About Kilogram and Stone
The kilogram is the SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by the old platinum-iridium prototype. It is the reference for every other mass unit on this site. The stone equals 14 pounds, exactly 6.35029318 kilograms. It survives almost exclusively for stating body weight in the UK and Ireland. One Kilogram equals 0.1574730444 Stone (1 kg = 0.1574730444 st). Kilogram to Stone conversion comes up most often in body weight outside the US and in groceries and food packaging worldwide, typically when figures need restating for body weight in the UK and Ireland.
Precision and Rounding: Metric-imperial mass factors are exact (1 lb = 0.45359237 kg by the 1959 agreement), so precision is purely a display choice. One decimal place is enough for body weight and cooking; nutrition labeling, pharmacy, and lab work need the full factor before rounding.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
