Celsius to Kelvin Converter
Fast and accurate conversion from Celsius to Kelvin.
Fast and accurate conversion from Celsius to Kelvin.
To convert Celsius to Kelvin, add 273.15. The formula is: K = °C + 273.15. For example, 20°C = 20 + 273.15 = 293.15 K.
Kelvin is an absolute temperature scale where 0 K is absolute zero (the coldest possible temperature). Celsius uses 0°C as the freezing point of water. The Kelvin scale has the same degree size as Celsius, but starts at absolute zero.
Kelvin is used in scientific calculations because it starts at absolute zero, making thermodynamic calculations simpler. Many physical laws and equations are expressed more elegantly using the Kelvin scale.
The freezing point of water is 273.15 K (0°C + 273.15). The boiling point is 373.15 K (100°C + 273.15). These are fundamental reference points in the Kelvin scale.
Yes, our Celsius to Kelvin converter allows bidirectional conversion. Enter any value in either Celsius or Kelvin and the tool will show both conversions for easy scientific calculations.
