Welcome to our Kelvin to Celsius converter, where you can easily convert one temperature to another. Whether you want to know how to convert Kelvin degrees to Celsius degrees or how to convert Celsius degrees to Kelvin degrees, we have covered both conversion methods in our tool and the article below.

We have also discussed the Kelvin to Celsius conversion formula to help you learn more about the Kelvin unit in this article. Want to know how much 1 Kelvin is in Celsius degrees or how much 0 Celsius is in Kelvin? Well, you'll find out soon!

How to use the Kelvin to Celsius converter

To use the Kelvin to Celsius converter:

Enter the temperature in Kelvin scale into the first field, e.g., 0 K.
The Kelvin to Celsius calculator will convert and display it in Celsius degrees in the second field, i.e., -273.15 °C.
You can also enter the temperature in Celsius degrees first to get the temperature in Kelvin degrees.
Additionally, the Celsius and Kelvin calculator has a unit switch in both fields, which you can also toggle to Fahrenheit if you ever need it.

Formula for Kelvin to Celsius conversion

Here is the formula for converting Kelvin to Celsius:

$\degree C = K - 273.15$

where:

$\degree C$ - temperature unit in Celsius degrees; and also
$K$ - absolute temperature unit in Kelvin.

The conversion formula from Celsius to Kelvin is the reverse:

$\degree C + 273.15$

Here are a few examples using the Celsius to Kelvin conversion equation:

Convert 1 Kelvin to Celsius.

Substituting values into the formula, we get:

$° C = 1 - 273.15$

Thus, when we convert 1 K to Celsius, we get -272.15 °C.
Now let's convert 100 degrees Celsius to Kelvin.

Rearranging the formula, we get:

$K = ° C + 273.15$

Substituting values:
$K = 100 + 273.15$

Thus, when we convert 100 °C to Kelvin, we get 373.15 K.

Of course, using our tool is a more convenient way to quickly apply the Celsius to Kelvin equation!

FAQ

Why is the Kelvin scale not measured in degrees?

Degrees are a relative term, while Kelvin is an absolute temperature scale with fixed endpoints. It has 0 as its lowest value, measuring the lowest possible temperature, i.e., when the atomic and molecular motion of every element stops.
