Celsius to Kelvin
1 °C = 274.15 K
How to convert celsius to kelvin
Enter the value in celsius (°C) above and the equivalent in kelvin (K) updates as you type. This conversion comes up when checking the weather in a country that uses a different scale than home.
- Normal body temperature is 37 °C, or 98.6 °F → that is 310.15 K in kelvin.
- A typical oven setting is 180 °C, about 350 °F → that is 453.15 K in kelvin.
- A home freezer should be around -18 °C, or 0 °F → that is 255.15 K in kelvin.
Typical situations: following recipes with oven settings from another region; interpreting a fever reading from a thermometer set to the wrong unit; understanding scientific material (lab protocols are always in Celsius or Kelvin).

Watch out for
- Converting oven temperatures too literally: fan-assisted ovens often need 20 °C less than the recipe says
- Fever thresholds do not shift linearly in feel: 38 °C (100.4 °F) is a fever, but "100" sounds scarier in Fahrenheit than it is
