About Kelvin to Celsius Conversion
Converting between Kelvin and Celsius is a common task in scientific and academic contexts. Our Kelvin to Celsius Converter makes this process simple and accurate.
Conversion Formula
The formula to convert Kelvin to Celsius is:
°C = K – 273.15
This formula takes the temperature in Kelvin and subtracts 273.15 to get the equivalent temperature in Celsius. The size of one unit in Kelvin is the same as one unit in Celsius; the scales just start at different points.
Understanding Kelvin and Celsius
The Kelvin and Celsius scales are two different ways of measuring temperature:
- Kelvin (K): The SI unit of temperature used in scientific applications. The Kelvin scale starts at absolute zero (0K), which is the theoretical temperature at which all thermal motion ceases. There are no negative temperatures in the Kelvin scale.
- Celsius (°C): Used in most countries worldwide for everyday temperature measurements. In the Celsius scale, water freezes at 0°C and boils at 100°C at standard atmospheric pressure.
Note that the Kelvin scale does not use the degree symbol (°). Temperatures are expressed simply as “K” rather than “°K”.

Frequently Asked Questions
Why is the Kelvin scale used in science?
The Kelvin scale is used in science because it starts at absolute zero, the theoretical temperature at which all thermal motion stops. This makes it useful for scientific calculations, especially in thermodynamics and physics, where having a scale that starts at zero thermal energy is important.
Why doesn’t Kelvin use the degree symbol?
Kelvin doesn’t use the degree symbol (°) because it’s an absolute temperature scale based on absolute zero, not an arbitrary point like the Celsius and Fahrenheit scales. It’s simply written as “K” rather than “°K”.
What is absolute zero?
Absolute zero (0 Kelvin or -273.15°C) is the theoretical temperature at which all molecular motion stops. It’s the lowest possible temperature that could exist in our universe, though it can never be fully reached in practice.
Are the increments in Kelvin and Celsius the same?
Yes, the size of one unit in the Kelvin scale is identical to one unit in the Celsius scale. A temperature difference of 1K is the same as a temperature difference of 1°C. The scales just start at different points.
