How to use the stone to kg converter
Type a weight in stone and read the kilograms next to it. For a weight such as 11 st 4 lb, pick "Stone + Pound" in the list: two fields appear, one for the stones and one for the pounds. The round button swaps the units to go from kg to stone, and the list below adds pounds, ounces and grams.
Examples: 8 st is 50.8 kg, 9 st 7 lb is 60.3 kg, 13 st is 82.6 kg and 15 st is 95.3 kg. In the other direction, 70 kg is 11 st 0.3 lb and 100 kg is 15 st 10.5 lb. Type the figure in the stone to kg converter and read both versions at once. For a quick check of a scale reading, it is faster than a calculator, and it also turns stones to kilograms in the other direction.
A stone is exactly 14 pounds, and a pound is exactly 0.45359237 kilogram (NIST), so 1 st is 6.35029318 kg. To convert stone to kg you multiply by 6.35029318. 10 st is 63.5 kg, 12 st is 76.2 kg, and 11 st 4 lb is 71.7 kg. The stone to kg converter keeps every decimal.
Body weight in the UK and Ireland
The stone is still how many people in the UK and Ireland say their body weight, while the rest of the world, including the US, uses kilograms or pounds. A US doctor, a gym app or a flight booking will ask for kilograms. The stone to kg converter gives you the figure at once.
Mental shortcut: multiply stones by 6.35, or by 6 and add 6 percent. 14 st is about 89 kg. In the other direction, divide kilograms by 6.35. Bathroom scales sold in Britain often switch between kg, lb and st, so type the reading as it appears.
Stones are mostly a body weight unit. For luggage, parcels and food, the world uses kilograms and pounds: see our guide to the 23 kg luggage limit for the check-in desk, where a stone figure would not help.
To go from pounds alone, the kg to lbs converter is the better fit.
