Temperature Converter
Instantly convert between °C, °F, and K.
Fahrenheit (°F)
68
20 Celsius (°C)
Kelvin (K)
293.15
Absolute zero is −273.15 °C (0 K). Kelvin values should stay at or above zero.
In-depth explanation
Convert temperatures between Celsius, Fahrenheit, and Kelvin for weather, cooking, and science. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
Multiply by 9/5, then add 32. Example: 20 °C → 68 °F. Kelvin is the SI scientific scale. 0 K is absolute zero (−273.15 °C). A change of 1 K equals a change of 1 °C.
About 37 °C or 98.6 °F for a typical resting adult. Tweak the inputs above to compare options, then copy or note the result you need.
Celsius and Kelvin steps are the same size; they only differ by 273.15 at zero. Fahrenheit has a different degree size, which is why you cannot add 32 and call it done without the 9/5 factor.
Cooking and weather are the usual uses. Body temperature is about 37 °C / 98.6 °F for a typical resting adult, with normal variation. Scientific work should stay in Kelvin or Celsius consistently.
