About this conversion
Stone to kilograms is a UK-specific conversion needed whenever a weight stated in the traditional British stone unit must be expressed in metric kilograms for medical, scientific, or international purposes. One stone = 14 pounds = 6.35029 kg exactly. This conversion is frequently needed for NHS medical records, gym equipment (which shows kg), international travel health forms, and cross-border clinical trials. British people often know their weight in stone but need kg for pharmacy apps, nutrition software, and European health assessments. Stone is not used in the US, Canada, or Australia — pounds and kilograms are the only units in those countries. The stone as a unit dates to medieval English markets and remains uniquely British.
