How to convert

Temperature uses an offset, not a simple ratio. Celsius converts to Kelvin via the standard temperature formula. For reference: 1 °C ≈ 274.15 K, and 1 K ≈ -272.15 °C.

About these units

Celsius

Definition: Celsius (symbol: °C) is a temperature scale where 0 °C is the freezing point of water and 100 °C is its boiling point at standard atmospheric pressure.
History: Anders Celsius proposed the inverted version of the scale (with 0° as boiling) in 1742; it was reversed to its current form shortly after his death.
Current use: Celsius is the everyday temperature scale in nearly every country and the standard scientific scale for non-thermodynamic work.

Kelvin

Definition: Kelvin (symbol: K) is the SI base unit of thermodynamic temperature. 0 K is absolute zero; the magnitude of one kelvin equals one degree Celsius.
History: Named after Lord Kelvin, who proposed the absolute thermodynamic scale in 1848. Redefined in 2019 by fixing the Boltzmann constant.
Current use: Kelvin is the standard temperature unit in physics, chemistry, and engineering — anywhere absolute temperatures matter, including color temperature in lighting and photography.
