How does the weight converter work?

All units are stored relative to a base unit (kilograms). The tool converts your input to kilograms, then to the target unit, ensuring accurate conversion between any pair of weight units.

How many pounds are in a kilogram?

One kilogram equals 2.20462 pounds. So a 70 kg person weighs about 154 pounds. This converter gives you the exact figure both ways.

A stone is a British unit equal to 14 pounds, or about 6.35 kilograms. It is still used for body weight in the UK and Ireland, and this converter supports it.

What is the difference between weight and mass?

Mass is the amount of matter in an object and stays constant; weight is the force of gravity on it. This converter uses standard mass units, which behave the same for everyday purposes.

Can I convert between metric tons and US tons?

Yes. A metric tonne is 1,000 kg, while a US short ton is about 907 kg. The converter distinguishes them clearly so you always get the right tonnage.
