How do you convert kilograms to pounds and other weight units?
Each value is converted to kilograms using its factor, then divided by the target unit factor; for example, 1 pound = 0.45359237 kg. So 1 kilogram = 2.2046 pounds = 35.274 ounces. Mass is the amount of matter; a metric tonne is 1,000 kg and a stone is 14 pounds.
Understanding your result
Mass is the amount of matter; on Earth we measure it as weight. The metric tonne is 1,000 kg, while a stone is 14 pounds.
Formula and method
Each value is converted to kilograms using its factor, then divided by the target unit factor. For example, 1 pound = 0.45359237 kg.
Assumptions and limitations
The tool converts mass using the exact international pound (1 lb = 0.45359237 kg). It does not distinguish mass from weight as a force, so it is not intended for physics problems that need newtons, and it uses the everyday avoirdupois ounce — not the troy ounce used for gold and silver, which is about 10% heavier.
Worked example
1 kilogram = 2.2046 pounds = 35.274 ounces.
