What Livres en kg does

Unit conversion expresses the same quantity in a different unit. Livres en kg multiplies the value by exact conversion factors, for example 1 lb = 0.45359237 kg and 1 ft = 0.3048 m, which are the international definitions. Temperature uses a formula with an offset instead of a single factor.

Results update while you type and are shown with up to six decimal places, formatted for your language. A list below the result shows the same value in every other unit of the same kind, which is handy for recipes, travel, shopping, fitness and school work.

Pound (lb)

The pound (symbol lb) is a unit of mass in the imperial and US customary systems. Since 1959, the international avoirdupois pound has been defined as exactly 0.45359237 kilograms, based on an agreement between the United States, the United Kingdom and other Commonwealth countries. One pound is divided into 16 ounces, and 14 pounds make one stone, a unit still used in the United Kingdom for body weight.

The pound is the everyday unit of weight in the United States for food, body weight and packages, and it is still common in the United Kingdom alongside the kilogram. As a practical reference, one kilogram is about 2.2 pounds, a one liter bottle of water weighs about 2.2 pounds, and a US package of four sticks of butter weighs one pound.

Kilogram (kg)

The kilogram (symbol kg) is the base unit of mass in the International System of Units (SI). Since 20 May 2019, it has been defined by fixing the value of the Planck constant at exactly 6.62607015 × 10⁻³⁴ joule seconds. Before that, it was defined by a platinum-iridium cylinder kept near Paris, called the International Prototype of the Kilogram.

The kilogram is used for weight and mass in almost every country, in science, trade, medicine and daily life. One kilogram equals 1000 grams and about 2.20462 pounds. As a practical reference, one liter of water has a mass of almost exactly one kilogram, and sugar and flour are often sold in one kilogram packs.

Tips for the best result

• Type numbers without thousands separators. Write 1500 or 1500.5, not 1,500.5, because a comma is read as the decimal separator.
• Data units here are decimal: 1 KB is 1,000 bytes and 1 GB is 1,000,000,000 bytes, as storage makers count. Some operating systems count in steps of 1,024 instead.
• Cups, fluid ounces and gallons use US measures. A UK (imperial) gallon is about 4.546 liters, not 3.785 liters as in the US.
• For body weight in stone, as used in the UK and Ireland, choose stone (st) in the weight list. One stone is exactly 14 pounds.

How Livres en kg works in your browser

Conversions use exact factors from international definitions, such as 1 pound = 0.45359237 kilograms and 1 foot = 0.3048 meters. Temperatures use the offset formulas for Celsius, Fahrenheit and Kelvin.

The calculation happens instantly in your browser as you type. Results are rounded for display, and numbers follow the formatting of your language.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. Livres en kg works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
