Weight measurements are used every day for health tracking, fitness goals, medical records, and international travel. However, different countries use different units of measurement. While kilograms (kg) are commonly used worldwide, stones (st) remain popular in the United Kingdom and Ireland. Understanding how to convert kilograms to stones can help you interpret weight measurements accurately and communicate them effectively.
A kilogram is the standard unit of mass in the metric system. It is widely used across most countries for measuring body weight, food products, luggage, and many other items. The kilogram is abbreviated as kg and forms the basis of the International System of Units (SI).
It’s not stubbornness. It’s just habit, passed down through generations. Doctors might write kilograms in your notes, but the number that sticks in your head is almost always in stone.

One stone equals exactly 6.35029 kilograms, or roughly 6.35 kg. So if someone says they weigh 10 stone, that's about 63.5 kg.
Divide your weight in kilograms by 6.35029 to get the total in stones. The whole number is your stones figure. Then multiply the decimal remainder by 14 to get the remaining pounds. For example, 80 kg ÷ 6.35029 = 12.598, so that's 12 stone 8.4 pounds.
70 kg works out to 11 stone and 0.2 pounds, so effectively 11 stone. It's one of the most commonly searched conversions, and it's a very common body weight for adults.
