Unit Converter FAQ

Which units can I convert with this tool?
The Unit Converter supports common length units such as millimeter, centimeter, meter, kilometer, inch, foot, yard and mile, and weight units such as milligram, gram, kilogram, metric ton, pound, ounce and stone.
How does the precision setting work?
You can choose between 2, 3, 4 and 6 decimal places. The converter rounds the visible output to the selected precision while keeping the internal calculation accurate, so you can switch precision without losing accuracy.
Is my data sent to a server?
No. All conversions run directly in your browser using JavaScript. Your input values are not uploaded, stored or tracked, and everything disappears when you close or refresh the page.
