The result updates instantly as you type, or as soon as you change either unit.

FAQ

Common questions

Is my data sent anywhere?
No. The conversion runs entirely in your browser — nothing is transmitted, logged, or stored.
What is Rankine or Réaumur used for?
Rankine is an absolute temperature scale using Fahrenheit-sized degrees, occasionally seen in older US engineering and thermodynamics references. Réaumur was a common scale in parts of Europe before Celsius became standard — you'll mostly encounter it in historical texts and some cooking references.
