Do you store my inputs?
No. Conversions run in your browser; we don’t send values to a server.
Why do temperature conversions look different?
Temperature uses formulas instead of simple multipliers, so we convert via Celsius first.
How precise are results?
We show up to 6 decimals and trim trailing zeros. For engineering-grade precision, use domain-specific tools.
Can I copy results?
Highlight and copy the result text directly. We keep the layout simple for quick copying.
