Fahrenheit To Kelvin Conversion Calculator

Enter A Temperature


Values Are Rounded To 5 Decimal Places

Use this calculator to quickly convert a temperature from degrees Fahrenheit (°F) to Kelvin (K).

Enter a temperature for an instant °F to K conversion - there is no need to press submit!

This calculator accepts values using both scales and so, if required, can be used to convert temperatures in Kelvin back to Fahrenheit.

If interested, this site has a Kelvin to Fahrenheit section, which also features a temperature conversion calculator, formula and tables.

Fahrenheit To Kelvin Formula

The calculator above uses the following formula to convert Fahrenheit to Kelvin:

Kelvin (K) = (Fahrenheit - 32) / 1.8 + 273.15

The worked example below shows how to convert to Kelvin from Fahrenheit using this formula.

If are using this formula to manually convert a temperature, check your result with the calculator.

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

This worked example shows how to convert a temperature in Fahrenheit to Kelvin using the formula: Kelvin (K) = (Fahrenheit - 32) / 1.8 + 273.15

Worked Example

Convert 80 Fahrenheit (°F) to Kelvin (K)

K = ( 80 - 32 ) / 1.8 + 273.15
= 48 / 1.8 + 273.15
= 26.6667 + 273.15
= 299.82 K
therefore, 80 Fahrenheit is equal to 299.82 Kelvin (K)
( to 2 decimal places )
