Converters
Weight Converter
Convert kilograms, pounds, ounces, grams, stone, and tons.
About This Tool
Convert everyday weight and mass values between metric, imperial, and US customary units while keeping similarly named tons distinct. The converter shows the same input across every supported unit so you can compare kilograms, pounds, ounces, stone, and tons at a glance. It is useful for package weights, recipes, product specifications, gym records, travel allowances, and measurement checks where the source and target units are known.
How To Use It
- Enter the weight or mass value.
- Choose the unit you are converting from.
- Choose the unit you want to convert to.
- Use Swap to reverse the conversion, or copy the numeric result.
Examples
Kilograms to pounds
Enter 10, choose Kilograms as the starting unit and Pounds as the target unit to get about 22.0462262185 pounds.
Ounces to grams
Enter 16, choose Ounces and Grams, and the result is 453.59237 grams, which is also one avoirdupois pound.
Compare ton definitions
A metric ton is 1,000 kilograms, a US short ton is 2,000 pounds, and an imperial long ton is 2,240 pounds. Select the named ton used by your source before converting.
Useful Notes
Supported units
The converter includes milligrams, grams, kilograms, metric tons, ounces, pounds, stone, US tons, and imperial tons.
Mass and weight wording
Mass describes the amount of matter, while weight is the force on that mass due to gravity. Everyday labels commonly use weight for kilograms and pounds, so this practical converter applies fixed mass-unit conversion factors rather than calculating gravitational force.
Ton is not one universal unit
A metric ton (tonne), US short ton, and imperial long ton have different sizes. The converter labels these separately; choosing only by the word ton can produce a materially wrong result.
Pounds and ounces here are avoirdupois units
General body, package, and grocery weights normally use avoirdupois pounds and ounces, where one pound equals 16 ounces. Troy ounces used for precious metals are a different unit and are not represented by the ordinary Ounces option.
Round to the source measurement
A converted value can display more decimal places than the original measurement justifies. For practical use, round the result to a precision consistent with the scale or source data you started with.
