Frequently asked questions
How do I convert weights?
Enter a value, pick the source and target units, and read the result instantly. For example: 1 kilogram = 2.20462 pounds. All math runs locally in your browser.
Is my data uploaded or stored?

How precise are the results?
Conversions use double-precision factors and display up to 6 significant decimals with trailing zeros stripped, so everyday and technical values both stay accurate.
