This page features a Kelvin to Celsius:


Kelvin To Celsius Conversion Calculator

Enter A Temperature


Values Are Rounded To 5 Decimal Places

Use this calculator to quickly convert a temperature from Kelvin (K) to degrees Celsius (°C).

Enter a temperature for an instant K to °C conversion - there is no need to press submit!

This calculator accepts values using both scales and so, if required, can be used to convert temperatures in Celsius back to Kelvin.

If interested, this site has a Celsius to Kelvin section, which also features a temperature conversion calculator, formula and tables.

Kelvin To Celsius Formula

The calculator above uses the following formula to convert Kelvin to Celsius:

Celsius (°C) = Kelvin - 273.15

The worked example below shows how to convert to Celsius from Kelvin using this formula.

If are using this formula to manually convert a temperature, check your result with the calculator.

How To Convert Kelvin To Celsius (K to °C)

This worked example shows how to convert a temperature in Kelvin to Celsius using the formula: Celsius (°C) = Kelvin - 273.15

Worked Example

Convert 300 Kelvin (K) to Celsius (°C)

°C = 300 - 273.15
= 26.85 °C
therefore, 300 Kelvin is equal to 26.85 Celsius (°C)

Albert Einstein is shown for illustrative purposes.
Anders Celsius (1701-1744), is the proponent of the Celsius temperature scale.
