The stone (st) is a traditional British unit of weight still used for body weight in the United Kingdom and Ireland. One stone equals 14 pounds or 6.35029318 kilograms exactly. Converting kg to stone therefore means dividing kilograms by 6.35029318, which is the same as multiplying by 0.157473. Body weight is usually quoted as stones and pounds rather than a decimal, so a 70 kg adult is 11 stone 0 pounds (11.0231 stone), and 80 kg is 12 stone 8.4 pounds (12.5978 stone). To turn the decimal into stones and pounds, multiply the fraction after the decimal point by 14. Stones are the one common unit where a kilogram figure does not fully replace the local convention, so UK readers converting a metric scale or a doctor’s note into a familiar number need this specific conversion. For pounds instead of stones, use the kg to lbs converter.
