About the Weight Calculator
The Weight Calculator is a free tool for everyday maths and number work. It runs right in your web browser, so there is nothing to download. Convert between pounds, kilograms, ounces, grams, stone, and metric tons.
How it works
Type a value, then pick what you want to change it into. The answer appears straight away. It all happens on your own device, so it is fast and nothing you type is sent away. Just check that you picked the right “from” and “to” so you get the answer you wanted.
