Kelvin to Celsius Converter K → °C
1 K equals -272.15 °C — note this scale uses an offset formula, not simple multiplication. Type a value below — the conversion happens instantly, entirely on your device.
300 K = 26.85 °C
300 kelvins = 26.85 degrees Celsius
300 × 1 − 273.15 = 26.85
These scales have different zero points, so the conversion multiplies by 1 and then shifts by −273.15.
How to convert kelvins to degrees Celsius
°C = K − 273.15 — subtract 273.15 from the kelvin value.
Example: 300 K = 26.85 °C.
To convert the other way: K = °C + 273.15 — or use the dedicated °C to K converter .

About the units
What is the Kelvin scale?
The kelvin (K) is the SI base unit of temperature, starting at absolute zero (0 K = −273.15 °C). A change of 1 K equals a change of 1 °C; kelvins are standard in science and engineering.
What is the Celsius scale?
Degrees Celsius (°C) set 0° at the freezing point of water and 100° at its boiling point (at standard pressure). It is the everyday temperature scale in almost every country.
