Temperature conversion catches most people at the wrong moment — in the kitchen with a recipe in the “wrong” units, or checking foreign weather before a trip. 0°C = 32°F (freezing), 100°C = 212°F (boiling), 20°C = 68°F (comfortable room temperature).

  1. Type a value in any of the three boxes — Celsius, Fahrenheit, or Kelvin.
  2. The other two update live.
  3. Scan the formula below if you want to do the math by hand.
  4. Clear the field when you're ready for a new value.
