Frequently asked questions
How do I convert temperatures?
Enter a value, pick the source and target units, and read the result instantly. For example: 20°C = 68°F = 293.15 K. All math runs locally in your browser.
Is my data uploaded or stored?
No. Unit conversion is pure arithmetic in your browser — nothing is sent, uploaded or stored.
How precise are the results?
Conversions use double-precision factors and display up to 6 significant decimals with trailing zeros stripped, so everyday and technical values both stay accurate.
