Kelvin To Fahrenheit Formula

Use this formula to convert a temperature in Kelvin (K) to Fahrenheit (°F).

Fahrenheit (°F) = Kelvin x 1.8 - 459.67

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

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 Fahrenheit 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 Daniel Gabriel Fahrenheit (1686-1736).

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

How To Convert Kelvin To Fahrenheit

Using the Kelvin to Fahrenheit formula: Fahrenheit (°F) = Kelvin x 1.8 - 459.67, these examples show how to convert a temperature in Kelvin to Fahrenheit.

Worked Example 1

How To Convert 200 Kelvin (K) to Fahrenheit (°F)

°F = ( 200 x 1.8 ) - 459.67
= 360 - 459.67
= -99.67 °F
therefore, 200 Kelvin is equal to -99.67 Fahrenheit (°F)

Worked Example 2

How To Convert 500 Kelvin (K) to Fahrenheit (°F)

°F = ( 500 x 1.8 ) - 459.67
= 900 - 459.67
= 440.33 °F
therefore, 500 Kelvin is equal to 440.33 Fahrenheit (°F)

Albert Einstein & his impostor are shown for illustrative purposes.
Daniel Gabriel Fahrenheit (1686–1736), is the proponent of the Fahrenheit temperature scale.

Formula Or Equation?

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

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
