    How to convert kelvins to degrees Celsius

    Worked example: 0 K = -273.15 °C

    K°C0100200273.15-273.15-1000absolute zerofreezing0 K-273.15 °C

    0 K − 273.15 = -273.15 °C

    Rule: °C = K − 273.15 — the zeros are 273.15 apart: water freezes at 273.15 K = 0 °C, and a kelvin is the same step as a degree Celsius.

    FAQ

    What is the formula to convert Kelvin to Celsius?

    °C = K − 273.15: subtract 273.15 from the temperature in kelvins. A change of 1 K is the same as a change of 1 °C.

    What is 0 Kelvin in Celsius?

    0 K = -273.15 °C — absolute zero, the lowest possible temperature.

    Why is the kelvin written without a degree sign?

    Since 1967 the kelvin has been an SI unit in its own right, not a degree: write 300 K and say “300 kelvins”; only °C and °F keep the degree sign.
