What is 0°C in Kelvin?
0°C is 273.1K.
Celsius to Kelvin
Type a temperature to convert it from Celsius to Kelvin. The two scales do not share a zero, so the conversion shifts as well as scales.
Result
Celsius and Kelvin, side by side
Celsius and Kelvin measure the same thing on different scales, and they start counting from different places. That is why the conversion is not a simple multiplication: 0°C comes out as 273.1K, not zero.
Going the other way, 0K is -273.1°C. Any converter that treats this as a ratio gets both directions wrong.
