Kelvin (K)
Temperature
Traceable to the kelvin, defined by fixing the Boltzmann constant at 1.380 649 × 10⁻²³ J/K. Celsius and Fahrenheit are exact affine transforms of the kelvin scale.

How to Convert Kelvin to Celsius
This conversion uses an offset formula, so it cannot be described by a single multiplication factor.
Formule : °C = K - 273.15
Inverse : K = °C + 273.15
Exemple Étape par Étape
- Start with your value in Kelvin. For example: 5 K
- Apply °C = K - 273.15
- The result is: -268.15 °C
À propos de Kelvin
The Kelvin scale is the SI unit of temperature that starts at absolute zero (−273.15°C). It is used extensively in scientific research.
Le saviez-vous : At 0 Kelvin (absolute zero), all molecular motion stops. It has never been fully achieved in a laboratory.
Utilisations courantes : physics, astronomy, chemistry.
À propos de Celsius
The Celsius scale sets 0°C as the freezing point and 100°C as the boiling point of water at standard pressure. It is used by most countries worldwide.
Le saviez-vous : Anders Celsius originally proposed a scale where 100° was freezing and 0° was boiling—it was later reversed!
Utilisations courantes : weather, cooking, science.
