°F = °C × 9/5 + 32 and K = °C + 273.15. Temperature scales have different zero points, so they are not simple multiples.

How to use

  1. Type the temperature (minus signs are fine).
  2. Pick the scale to convert to.
  3. See all four scales in the table.

Good to know

°F = °C × 9/5 + 32 and °C = (°F − 32) × 5/9. Kelvin starts at absolute zero: K = °C + 273.15. The scales have different zero points, so you cannot just multiply.

Body temperature: about 37 °C = 98.6 °F is the traditional average; a fever is usually taken as 38 °C (100.4 °F) or higher. Thermometers in India show either scale, so this helps compare readings.

Oven settings: 180 °C = 356 °F (often written as 350 °F) and 200 °C = 392 °F. −40 is the one temperature that is the same in °C and °F.
