Frequently Asked Questions
What units does this weight converter support?
Common units include grams, kilograms, pounds, ounces, stone, and metric/US tons.
How many pounds are in a kilogram?
One kilogram equals approximately 2.205 pounds.
What is a stone, and how many pounds is it?
A stone is a British imperial unit equal to 14 pounds, still commonly used for body weight in the UK and Ireland.
Is weight the same as mass?
In everyday and scientific usage, mass (measured in kg or lb) is often used interchangeably with weight, though technically weight is the force of gravity on a mass — this converter handles the common mass-unit conversions people mean by "weight."
What's the difference between a US ton and a metric ton?
A US (short) ton is 2,000 pounds, while a metric ton (tonne) is 1,000 kilograms (about 2,204.6 pounds) — they are not the same value.

Is my data saved anywhere?
No — conversions run in your browser and the values you enter are not stored or sent to a server.

Yes — converting grams to ounces or pounds is a common need when following recipes from a different country's measurement system.
How many ounces are in a pound?
There are 16 ounces in one pound.
