Kg to Lbs Converter
One kilogram is 2.20462262185 pounds, because the international pound is defined as exactly 0.45359237 kilograms and the conversion is a division by that number. This page opens with kilograms selected on the left and pounds on the right, so the pair is already set even if you last used the converter for something else. Under the result the same amount is printed in milligrams, grams, ounces, stone, tonnes and US short tons at once, which is the part most kg to lbs pages leave out: you rarely know you wanted stone until you see it.
1 kg in every mass unit
Common questions
- How many pounds is 1 kg?
- 2.20462262185 lb, which is what this page shows for 1 kg at the 12 significant digits it works to. The everyday shorthand is 2.2 lb, and it is close: it runs short by about 0.0046 lb for every kilogram, which adds up to roughly three quarters of an ounce at 10 kg.
- How do I convert kg to lbs in my head?
- Double it and add 10 percent. For 70 kg that is 140 plus 14, so 154 lb, against the 154.323583529 lb this page computes: about a third of a pound light. The trick works because 2.2 is 2 plus a tenth of 2, and it runs about 0.2 percent under the true figure, which is fine for a suitcase and not for a shipping label.
- Is the kilogram to pound conversion exact?
- The definition is. Since 1959 the international avoirdupois pound has been exactly 0.45359237 kg, which is why entering 1 lb here returns 0.45359237 kg with nothing trailing and 100 lb returns 45.359237 kg. Going the other way divides by that number and the decimal does not terminate, so 1 kg is shown as 2.20462262185 lb, rounded to 12 significant digits rather than carried further.
- What is 70 kg in stone and pounds?
- 154.323583529 lb, or 11.0231131092 stone. The list under the result gives stone as a decimal rather than as stone and pounds, so multiply the fraction by 14 to finish the job: 0.0231131092 times 14 is 0.32 lb, which makes 70 kg eleven stone and about a third of a pound.
- Can I convert pounds back to kilograms here?
- Yes. The swap button between the two boxes flips the pair to pounds into kilograms, and the list underneath then shows kilograms alongside grams, ounces and stone. Uncommon mass units are hidden until you ask: the readout has a switch that adds long tons, carats and grains.
- Is this a weight or a mass conversion?
- Mass. The readout under the boxes names the category Mass and the base unit kilogram, and both the kilogram and the pound are units of mass, so the ratio never changes. Bathroom and luggage scales report weight but are calibrated for gravity at the Earth's surface and labelled in kilograms or pounds, so for anything you would weigh in a kitchen, a gym or an airport this is the number you want.
- Is anything I type sent anywhere?
- No. The conversion is one multiplication and one division running in your browser, and the page keeps working with no network once it has loaded. The number you last typed is kept on your own device so the page can restore it, and Start over at the top of the page clears it.
Conversion factors are the exact legal definitions where one exists. An inch is exactly 2.54 cm and a pound exactly 0.45359237 kg, so those conversions are exact rather than approximate. Temperature uses offsets rather than factors, and that is shown in the working.
