Kelvin to Degrees Celsius (K to °C)
Convert kelvin to degrees Celsius with the formula °C = K − 273.15. Conversion table and worked examples, with JSON API and MCP access.
Formula
°C = K − 273.15
°C = K − 273.15 — reverse: K = °C + 273.15
Non-linear conversion: the formula above is applied directly (no single multiplication factor).
Worked examples
- 300 K = 26.85 °C
- 273.15 K = 0 °C
- 0 K = -273.15 °C

FAQ
What is the formula to convert kelvin to degrees Celsius?
°C = K − 273.15. For example, 300 K = 26.85 °C.
How do I convert degrees Celsius back to kelvin?
K = °C + 273.15; the degrees Celsius-to-kelvin page applies it directly.
Why is there no single multiplication factor?
Temperature scales have different zero points, so the conversion is an affine formula (scale and offset), not a plain multiplication.
