This page features a Celsius to Kelvin:


Celsius To Kelvin Conversion Calculator

Enter A Temperature


Values Are Rounded To 5 Decimal Places

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

Enter a temperature for an instant °C to K 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 Kelvin back to Celsius.

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

Celsius To Kelvin Formula

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

Kelvin (K) = Celsius + 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 Celsius To Kelvin (°C to K)

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

Worked Example

Convert 10 Celsius (°C) to Kelvin (K)

K = 10 + 273.15
= 283.15 K
therefore, 10 Celsius (°C) is equal to 283.15 Kelvin (K)

Albert Einstein is shown for illustrative purposes.
William Lord Kelvin (1824–1907), is the proponent of the Kelvin temperature scale.
