Kelvin to Celsius Conversion
Kelvin and Celsius are related by a formula rather than a fixed ratio — see the worked example below.
1 Kelvin = -272.15 Celsius
How to convert Kelvin to Celsius
- Celsius to Fahrenheit
°F = °C × 9/5 + 32 - Fahrenheit to Celsius
°C = (°F − 32) × 5/9 - Celsius to Kelvin
K = °C + 273.15 - Fahrenheit to Rankine
°R = °F + 459.67
Example: 10 K = -263.15 °C.
Watch out: To convert a temperature change rather than a reading — for example "the oven got 10 degrees hotter" — use the Temperature Interval converter, which has no offset.

Frequently asked questions
What is 1 Kelvin in Celsius?
1 Kelvin (K) is -272.15 Celsius (°C).
What is 1 Celsius in Kelvin?
1 Celsius (°C) is 274.15 Kelvin (K).
How do I convert Kelvin to Celsius?
Kelvin and Celsius are not related by a single multiplication factor. The formulas used are: Celsius to Fahrenheit: °F = °C × 9/5 + 32; Fahrenheit to Celsius: °C = (°F − 32) × 5/9; Celsius to Kelvin: K = °C + 273.15; Fahrenheit to Rankine: °R = °F + 459.67. For example, 5 K is -268.15 °C.
How many units does the temperature converter support?
It converts between 4 units: Celsius, Fahrenheit, Kelvin, Rankine.
What should I watch out for when converting temperature?
To convert a temperature change rather than a reading — for example "the oven got 10 degrees hotter" — use the Temperature Interval converter, which has no offset.
