How to Convert Celsius to Kelvin Online
Enter the temperature in Celsius and get the Kelvin equivalent. The conversion is simple: add 273.15. Kelvin uses the same degree size as Celsius but starts at absolute zero (-273.15°C).
Why Convert Celsius to Kelvin?
Kelvin is the SI unit of temperature used in physics, chemistry, and engineering. Scientific equations often require temperatures in Kelvin because it is an absolute scale — zero Kelvin means zero thermal energy. This converter is essential for students, researchers, and engineers working with thermodynamic calculations.
Frequently Asked Questions
What is 0°C in Kelvin? 0°C equals 273.15 K — the freezing point of water.
Does Kelvin use degree symbols? No. Kelvin temperatures are written as just "K" without a degree symbol (e.g., 300 K, not 300°K).
