Kelvin vs Celsius

Kelvin and Celsius are two closely related temperature scales used across science and everyday life.

While Celsius is common globally for weather forecasts and everyday cooking, Kelvin is the standard SI unit for thermodynamic temperature, heavily utilized in physics, astronomy, and chemical engineering.

The two scales share the same incremental size—a change of 1 K is identical to a change of 1°C. However, Kelvin starts at absolute zero (0 K, which equals -273.15°C), the theoretical point where all molecular motion ceases.
