How to convert 273.15 K to °C

Follow these steps to check the answer yourself.

  1. 1

    Write the conversion formula

    Celsius is kelvin shifted by 273.15.

    °C = K − 273.15

  2. 2

    Substitute the Kelvin value

    Replace K with 273.15.

    °C = 273.15 − 273.15

  3. 3

    Subtract 273.15

    This gives the temperature in Celsius.

    273.15 − 273.15 = 0

Answer: 273.15 K = 0°C

Is 273.15 K hot or cold?

273.15 K (0°C) reads as cold on the thermometer: coat weather. Typical context: cold to cool weather.

273.15 K is the freezing point of water.

Quick mental math

To estimate Kelvin to Celsius in your head, subtract 273 from the kelvin value.

273.15 − 273 = 0.15°C (exact answer: 0°C)

Dropping the 0.15 is fine for everyday use, but keep it for lab and engineering work.

To go the other way, use the Kelvin converter: 0°C converts back to 273.15 K.

Frequently asked questions

What is 273.15 K in Celsius?

273.15 K equals 0°C. This is calculated with the standard Kelvin to Celsius formula.

How do I convert 273.15 Kelvin to Celsius?

To convert Kelvin to Celsius, subtract 273.15. For 273.15 K the result is 0°C.

Is 273.15 K hot or cold?

0°C is quite cold - typical winter weather. Heavy clothing is recommended.

What is the formula for Kelvin to Celsius conversion?

The formula is: °C = K − 273.15

Good to know

  • Anders Celsius proposed his scale in 1742. It was originally inverted, with 0 for boiling water and 100 for freezing; the order was flipped soon after his death.
  • The kelvin is the SI base unit of temperature. Since 2019 it has been defined by fixing the value of the Boltzmann constant, not by the properties of water.
  • Kelvin is written without a degree sign: 300 K, not 300°K.
  • A change of 1°C or 1 K equals a change of 1.8°F.
