Kelvin to Celsius

Temperatures in scientific papers, data sheets and astronomy articles are given in kelvin, the SI unit whose zero is absolute zero. To turn them into the familiar Celsius scale, subtract 273.15: °C = K − 273.15. Nothing else changes, because a kelvin and a degree Celsius are the same size.

Typical values

  • 0 K = −273.15 °C (absolute zero)
  • 77 K = −196.15 °C (liquid nitrogen)
  • 195 K = −78.15 °C (dry ice)
  • 273.15 K = 0 °C (ice melts)
  • 293.15 K = 20 °C (room temperature)
  • 300 K = 26.85 °C (a common "round" value in physics problems)
  • 310.15 K = 37 °C (body temperature)
  • 373.15 K = 100 °C (water boils)
  • 1000 K = 726.85 °C

Reading kelvin values in everyday contexts

Light bulbs and screens. Colour temperature in kelvin is not a temperature you can feel; 2700 K describes the warm colour of an incandescent bulb, 6500 K the bluish white of daylight. Converting these to Celsius is mathematically valid (2700 K = 2427 °C) but meaningless for choosing a lamp.

Weather and climate science. Global temperature datasets are often stored in kelvin to avoid negative numbers. A monthly mean of 288 K is 14.85 °C — close to the Earth's average surface temperature.

Cryogenics. Liquid helium boils at 4.2 K, which is −268.95 °C. At these temperatures Celsius numbers become clumsy, which is exactly why kelvin exists.

Common mistakes

Do not write "°K" — the unit is just K. And remember that differences are the same in both scales: a rise of 10 K is a rise of 10 °C, with no 273.15 involved.
