How many stone in 1 kg?
1 kg = 0.1574730444 st. The other way round: 1 st = 6.35029318 kg. The kilogram is the SI base unit of mass; since 20 May 2019 it is defined through the Planck constant instead of a metal prototype kept near Paris. One stone is 14 pounds, about 6.35 kg. In the UK and Ireland body weight is still often stated in stones and pounds, e.g. 11 st 4 lb.

How to use
- 1Pick a category — length, weight, temperature, volume, area, speed, data, time, pressure or energy.
- 2Choose the “from” and “to” units, or press swap to reverse them.
- 3Type a value in either field — the other side updates as you type.
- 4Adjust the decimal precision and check the conversion table for common values.
Exact conversion factors
Many imperial units are defined exactly in metric terms: 1 inch = 2.54 cm, 1 foot = 0.3048 m, 1 mile = 1.609344 km, 1 pound = 0.45359237 kg and 1 US gallon = 3.785411784 litres. The converter uses these definitions, so results are as precise as the decimals you choose to show. The formula is displayed in words — for example “multiply by 2.54” — so you can repeat the calculation by hand.
Temperature is different
Celsius, Fahrenheit and Kelvin do not share a zero point, so temperature cannot be converted with a single factor. °F = °C × 9/5 + 32 and °C = (°F − 32) × 5/9; Kelvin is Celsius + 273.15. That is why 0 °C is 32 °F, while a 10-degree change in Celsius is an 18-degree change in Fahrenheit.
US vs UK units and data sizes
A US gallon (3.785 L) is smaller than an imperial UK gallon (4.546 L), and US fluid ounces differ slightly from UK ones — check which system your recipe or spec uses. For data sizes, storage makers use decimal units (1 GB = 1,000 MB), while operating systems often count in binary units (1 GiB = 1,024 MiB), which is why a new drive shows less capacity than the label.
