Frequently asked questions
What is 1 kelvin in celsius?
1 kelvin is -272.15 °C. Temperature scales have different zero points, so you cannot multiply by that figure for other values. Use °C = K − 273.15 instead.
How do I convert kelvin to celsius?
Use °C = K − 273.15. For example, 300 kelvin gives 26.85 °C. Enter your own value above and the converter does the arithmetic for you.
How do I convert celsius back to kelvin?
Use the Celsius to Kelvin converter, or invert the factor by dividing instead of multiplying.
Is this conversion exact?
Temperature scales differ by an offset as well as a ratio, which is why you cannot convert them by multiplying alone.
