## Rankine To Kelvin Formula

Use this formula to convert a temperature in Rankine (°R) to Kelvin (K).

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

Temperature scales are usually named after the person who created them. The temperature scales used in this formula were created by William John Macquorn Rankine (1820-1872), and William Thomson, Baron Kelvin (1824-1907).

The Kelvin scale was proposed in 1848 and the Rankine scale in 1859. It's probable that William Rankine created this formula for converting Rankine to Kelvin.

## How To Convert Rankine To Kelvin

Using the **Rankine to Kelvin formula: Kelvin (K) = Rankine / 1.8**, these examples show how to convert a temperature in Rankine to Kelvin.

#### Worked Example 1

### How To Convert 500 Rankine (°R) to Kelvin (K)

K = | 500 / 1.8 |

= | 277.78 K |

∴ | therefore, 500 Rankine (°R) is equal to 277.78 Kelvin (K) ( to 2 decimal places ) |

#### Worked Example 2

### How To Convert 650 Rankine (°R) to Kelvin (K)

K = | 650 / 1.8 |

= | 361.11 K |

∴ | therefore, 650 Rankine (°R) is equal to 361.11 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 Rankine to Kelvin?

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
