Convert everyday weight and scientific mass measurements between metric and imperial units.
The tool uses kilograms as its internal reference and keeps the international avoirdupois definitions for pounds and ounces. A metric tonne is 1,000 kilograms.
Choose a measurement category and two units, then enter any finite positive or negative value allowed by that measurement. Adjust decimal places when the result needs more detail. Swap Units reverses the direction without discarding the current value.
