About Celsius and Kelvin
The Celsius to Kelvin conversion is straightforward: K = °C + 273.15. The Kelvin scale is the SI base unit of temperature, developed by Lord Kelvin in 1848, where 0 K (absolute zero) is the theoretical point where all molecular motion stops. Kelvin uses the same temperature interval as Celsius but starts at absolute zero instead of water freezing. Scientists use Kelvin for thermodynamics, chemistry, and astrophysics because it has no negative values and directly relates to thermal energy.
