Common values, converted exactly
| kelvins (K) | degrees Celsius (°C) |
|---|---|
| 0 K | -273.15 °C |
| 77 K | -196.15 °C |
| 200 K | -73.15 °C |
| 273.15 K | 0 °C |
| 288 K | 14.85 °C |
| 293 K | 19.85 °C |
| 298 K | 24.85 °C |
| 300 K | 26.85 °C |
| 310 K | 36.85 °C |
| 373.15 K | 100 °C |

To convert kelvin to Celsius, apply °C = K − 273.15. For example, 298 K = 24.85 °C.
The Celsius scale is the kelvin scale shifted by exactly 273.15: °C = K − 273.15. The step is the same size on both, so a change of 1 K is a change of 1 °C. Absolute zero is 0 K, or −273.15 °C. A kelvin takes no degree sign: it is 300 K, not 300 °K.
Everything on this page is computed in your browser from the exact definitions above — the table is not a stored list of pre-rounded answers, and neither is the converter. For a unit not covered here, the full unit converter handles length, weight, volume, temperature and cooking measures.
How many degrees Celsius is 298 K?
298 K = 24.85 °C. °C = K − 273.15, so any amount converts the same way — the table on this page lists the values most often looked up.
What is the formula for converting kelvin to Celsius?
°C = K − 273.15. The Celsius scale is the kelvin scale shifted by exactly 273.15: °C = K − 273.15. The step is the same size on both, so a change of 1 K is a change of 1 °C. Absolute zero is 0 K, or −273.15 °C. A kelvin takes no degree sign: it is 300 K, not 300 °K.
Is the kelvin to Celsius conversion exact?
Yes. The kelvin and Celsius scales are defined against each other exactly, so the conversion introduces no error — only the rounding you choose to apply to the answer.
How do I convert degrees Celsius back to kelvins?
Use the reverse of the same relationship; the celsius to kelvin page has its own table and converter.
