Conversion formula

T(K) = T(°C) + 273.15

T(°C) = T(K) − 273.15

How to convert Celsius to Kelvin

Apply this formula to the temperature value: T(K) = T(°C) + 273.15. Scales can have different zero points; multiplying by one factor is not always enough.

For example, 1 °C = 274.15 K and 10 °C = 283.15 K.

What is Celsius?

Celsius (°C): Used for weather and everyday temperature readings. Its interval size matches kelvin, but its zero point differs. 0 °C = 273.15 K.

What is Kelvin?

Kelvin (K): An absolute temperature scale used in gas laws and physics. It is written without a degree sign. 0 K = −273.15 °C.
