Fahrenheit To Kelvin Formula
Use this formula to convert a temperature in Fahrenheit (°F) to Kelvin (K).
If required, there are worked examples below which use this formula to show how to convert a temperature in Fahrenheit 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 Fahrenheit to Kelvin calculator.
Temperature scales are usually named after the person who created them. The temperature scales used in this formula were created by Daniel Gabriel Fahrenheit (1686-1736) and William Thomson, Baron Kelvin (1824-1907).
Given the Kelvin scale was invented many years after the Fahrenheit scale, it's probable William Kelvin also created this formula for converting Fahrenheit to Kelvin.
How To Convert Fahrenheit to Kelvin
Using the Fahrenheit to Kelvin formula: Kelvin (K) = ( Fahrenheit - 32 ) / 1.8 + 273.15, these examples show how to convert a temperature in Fahrenheit to Kelvin.
Worked Example 1
How To Convert 100 Fahrenheit (°F) To Kelvin (K)
| K = | ( 100 - 32 ) / 1.8 + 273.15 |
| = | 68 / 1.8 + 273.15 |
| = | 68 / 1.8 + 273.15 |
| = | 310.93 K |
| ∴ | therefore, 100 Fahnreheit is equal to 310.93 Kelvin (K) ( to 2 decimal places ) |

Worked Example 2
How To Convert 150 Fahrenheit (°F) to Kelvin (K)
| K = | ( 150 - 32 ) / 1.8 + 273.15 |
| = | 118 / 1.8 + 273.15 |
| = | 65.55 + 273.15 |
| = | 338.71 K |
| ∴ | therefore, 150 Fahrenheit is equal to 338.71 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 Fahrenheit temperature scale.
Formula Or Equation?
Is a formula, an equation, or both used to convert Fahrenheit 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
