## Kelvin To Celsius Formula

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

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

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 Kelvin to Celsius calculator.

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

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

## How To Convert Kelvin To Celsius

Using the **Kelvin to Celsius formula: Celsius (°C) = Kelvin - 273.15**, these examples show how to convert a temperature in Kelvin to Celsius.

#### Worked Example 1

### How To Convert 200 Kelvin (K) to Celsius (°C)

°C = | 200 - 273.15 |

= | -73.15 °C |

∴ | therefore, 200 Kelvin is equal to -73.15 Celsius (°C) |

#### Worked Example 2

### How To 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 & his impostor are shown for illustrative purposes.*

Anders Celsius (1701-1744), is the proponent of the Celsius temperature scale.

## Formula Or Equation?

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

I regard the formulae* , on the Calculate and Convert section of this website, as being formulae

andequations -each formula is in the form of an equation.* 'formulae', (

and formulas), are the plural of formula
