Frequently asked questions
What is 1 celsius in kelvin?
1 celsius is 274.15 K. Temperature scales have different zero points, so you cannot multiply by that figure for other values. Use K = °C + 273.15 instead.
How do I convert celsius to kelvin?
Use K = °C + 273.15. For example, 37 celsius gives 310.15 K. Enter your own value above and the converter does the arithmetic for you.
How do I convert kelvin back to celsius?
Use the Kelvin to Celsius 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.
