Mass & Weight Converter
Convert a mass or weight between metric and imperial units such as kilograms, pounds and stone.
Result
Worked example
1 kilogram is approximately 2.20462 pounds.
How it works
Xiliro converts common everyday mass units (kilograms, grams, pounds, ounces, stone and more), using exact internationally defined constants. This is a mass converter, not a force/weight-in-newtons calculator: it converts the same units people already call "weight" in everyday speech. Enter zero or a positive value; the displayed result may be rounded for readability, but the underlying calculation always uses the full, unrounded value.
What this result means
The converted value uses exact, defined conversion factors between the two units you chose.
Assumptions and limitations
- Negative values are rejected, since a mass or weight cannot be negative.
