The UK is a "mixed-units" country: body weight in stone, ingredients in pounds, medicine in grams. This tool covers kilograms, grams, pounds, ounces, and stone (1 st = 14 lb, the unit Britons use for body weight) .
Frequently asked questions
What is a stone in kg?
1 stone (st) = 6.35 kg = 14 pounds. The stone is used almost exclusively in the UK and Ireland for body weight — e.g. "I weigh 11 stone" means about 70 kg.
How do I convert kg to stone?
Divide the kilograms by 6.35 to get stone. For example, 70 kg ÷ 6.35 = 11 stone. Or divide by 0.4536 to get pounds first, then by 14 for stone.
How many pounds in a stone?
There are 14 pounds (lb) in 1 stone. So 11 stone = 154 lb, and 1 lb = 0.0714 stone. UK body weight is usually given as stone and pounds together, like 11 st 4 lb.
Why does the UK still use stone and pounds?
Body weight in the UK is conventionally given in stone and pounds (e.g. 11 st 6 lb), not just pounds like the US. Most other weights (food, goods) are now metric, but body weight stayed imperial by habit.
