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

The conversion from Fahrenheit to Kelvin is straightforward: one degree Fahrenheit is equivalent to a Kelvin multiplied by 5/9, minus 32, and then adding 273.15. Therefore, to perform the conversion, simply subtract 32 from the temperature in Fahrenheit, multiply the result by 5/9, and add 273.15.

Formula

This formula represents the conversion from Fahrenheit to Kelvin by subtracting 32 from the Fahrenheit value, then multiplying the result by 5/9, and finally adding 273.15.
Kelvin=(Fahrenheit−32)×59+273.15\text{Kelvin} = (\text{Fahrenheit} - 32) \times \frac{5}{9} + 273.15

Conversion Example: Fahrenheit to Kelvin

With these steps, you can easily convert degrees Fahrenheit to Kelvin without the need for a calculator. Below, we provide practical examples to better understand the process.

Example 1

Convert 95 degrees Fahrenheit to Kelvin.

This example shows how to convert 95 degrees Fahrenheit to Kelvin. First, subtract 32 from 95, obtaining 63. Then, multiply this result by 5/9, obtaining 35. Finally, add 273.15, which results in 308.15 Kelvin.
Kelvin=(95−32)×59+273.15=308.15 K\text{Kelvin} = (95 - 32) \times \frac{5}{9} + 273.15 = 308.15\,\text{K}

Result: 95 degrees Fahrenheit equals 308.15 Kelvin.

Example 2

Convert -22 degrees Fahrenheit to Kelvin.

This example shows how to convert -22 degrees Fahrenheit to Kelvin. First, subtract 32 from -22, obtaining -54. Then, multiply this result by 5/9, obtaining -30. Finally, add 273.15, which results in 243.15 Kelvin.
Kelvin=(−22−32)×59+273.15=243.15 K\text{Kelvin} = (-22 - 32) \times \frac{5}{9} + 273.15 = 243.15\,\text{K}

Result: -22 degrees Fahrenheit equals 243.15 Kelvin.
