Celsius To Kelvin Formula

Use this formula to convert a temperature in Celsius (°C) to Kelvin (K).

Kelvin (K) = Celsius + 273.15

If required, there are worked examples below which use this formula to show how to convert a temperature in Celsius to a temperature in Kelvin.

As with any math calculation and conversion, it's good practice to double check your results. If you are using this formula for your own conversions, you can check your result with the Celsius to Kelvin calculator.

Temperature scales are usually named after the person who created them. The temperature scales used in this formula were created by Anders Celsius (1701–1744) and William Thomson, Baron Kelvin (1824-1907).

Given the Kelvin scale was invented many years after the Celsius scale, it's probable Lord Kelvin William Thomson also created this formula for converting Celsius to Kelvin.

How To Convert Celsius To Kelvin

Using the Celsius to Kelvin formula: Kelvin (K) = Celsius + 273.15, these examples show how to convert a temperature in Celsius to Kelvin.

Worked Example 1

How To Convert 50 Celsius (°C) to Kelvin (K)

k = 50 + 273.15
= 323.15 K
therefore, 50 Celsius (°C) is equal to 323.15 Kelvin (K)
( to 2 decimal places )

Worked Example 2

How To Convert 75 Celsius (°C) to Kelvin (K)

K = 75 + 273.15
= 348.15 K
therefore, 75 Celsius (°C) is equal to 348.15 Kelvin (K)
( to 2 decimal places )

Albert Einstein & his impostor are shown for illustrative purposes.
William Thomson, Baron Kelvin (1824-1907), is the proponent of the Kelvin temperature scale.

Formula Or Equation?

Is a formula, an equation, or both used to convert Celsius to Kelvin?

I regard the formulae* , on the Calculate and Convert section of this website, as being formulae and equations - each formula is in the form of an equation.

* 'formulae', (and formulas), are the plural of formula
