About this temperature converter
This tool converts between Celsius, Fahrenheit, and Kelvin. Unlike length or weight, temperature scales don't share a common zero point, so the conversion isn't a simple multiplication — this tool handles that math for you instantly, entirely in your browser, with no network request.
Scales covered
- Celsius (°C) — the metric scale where water freezes at 0° and boils at 100°, used for everyday temperature almost everywhere outside the US.
- Fahrenheit (°F) — the scale where water freezes at 32° and boils at 212°, still the everyday standard in the United States.
- Kelvin (K) — the SI base unit of temperature, starting at absolute zero (−273.15°C), used throughout science and engineering.
