FAQ
How do I use the Unit Converter?
Enter a value, pick the From and To units, and the result updates
instantly. Works for length, weight, and temperature.
Does this tool send data to a server?
No. All conversions are computed locally in your browser.
Why are there decimals in results?
Some unit ratios are non-terminating (e.g., miles to kilometers). We
round to a reasonable number of decimals while keeping accuracy.
Are these conversions exact?
SI-based conversions are exact by definition (e.g., 1 km =
1000 m). Others like miles↔kilometers use standard precise
constants.
