Kelvin to Celsius Converter
Use this page to convert kelvin values into celsius, with background details, formulas, a worked example, and a quick conversion table.
Conversion formula
This conversion uses an offset formula rather than a single multiplier because the temperature scales start from different zero points.
K to deg C: Apply the scale formula and then add or remove the required offset.
Example: 25 K = -248.15 deg C
Kelvin
Kelvin uses the same interval size as Celsius, with absolute zero at 0 K.
History: It was developed for thermodynamics and later integrated into the SI system.
Current use: Kelvin is used in science, engineering, and color temperature references.
Also written as K, kelvins.
Celsius
The Celsius scale places water freezing at 0 and boiling at 100 under standard atmospheric pressure.
History: The scale evolved from the work of Anders Celsius and later refinements.
Current use: Celsius is the default temperature scale for weather and daily life in most countries.
Also written as deg C, °C, C, degC, degree C, degrees C, degree Celsius, degrees Celsius, centigrade.

Frequently asked questions
What is 0 Kelvin in Celsius?
0 Kelvin equals -273.15 Celsius.
What is 100 Kelvin in Celsius?
100 Kelvin equals -173.15 Celsius.
Why does Kelvin to Celsius conversion need more than a multiplier?
Temperature scales like Kelvin and Celsius start from different zero points, so the conversion uses both a scale factor and an offset.
What is 25 Kelvin in Celsius?
25 Kelvin equals -248.15 Celsius.
