Kelvin to Celsius Converter
Scientific papers, sensor datasheets, and astronomy articles quote temperatures in kelvin, but human intuition runs on Celsius. Converting kelvin to Celsius translates lab numbers into something you can feel: 293 K is a pleasant 20°C room, 373 K is boiling water. The formula is °C = K − 273.15 — just subtract the absolute-zero offset. The converter above works instantly in both directions, the table covers values from cryogenics to ovens, and the FAQs answer the classic questions, including whether kelvin can ever go negative.

Frequently Asked Questions
How many celsius are in 293.15 kelvin?
293.15 kelvin = 20 celsius. Just apply the conversion to any value with the converter above.
What is the formula to convert kelvin to celsius?
To convert kelvin to celsius, subtract 273.15 from the Kelvin temperature. In short: °C = K − 273.15.
Can Kelvin be negative?
No. 0 K is absolute zero — the lowest temperature physically possible — so negative kelvin values do not exist. (In exotic quantum systems physicists talk about ‘negative temperatures,’ but those are actually hotter than any positive temperature, not colder.) 293.15 K, a mild room, is 20°C.
How do I convert celsius back to kelvin?
Simply reverse the math: to go from celsius to kelvin, use K = °C + 273.15. Or use our dedicated Celsius to Kelvin converter.
