Fahrenheit to Kelvin Converter

Change a Fahrenheit temperature reading into kelvin in one calculation, without rounding an intermediate Celsius result.

How to use Fahrenheit to Kelvin Converter

1. Enter Fahrenheit. 2. Ordinary temperature conversion on the stated Celsius/Fahrenheit/Kelvin basis, subject to its supported lower bound and output range. 3. Select Convert or press Enter from a single-line field. In multiline text fields, Enter inserts a line break. 4. Select Copy result to copy the answer, or Reset to clear the form and result.

Why use this tool?

Use Fahrenheit to Kelvin Converter when you need kelvin. Ordinary temperature conversion on the stated Celsius/Fahrenheit/Kelvin basis, subject to its supported lower bound and output range.

How the calculation works

Kelvin = (Fahrenheit − 32) × 5/9 + 273.15. Combining the Fahrenheit-to-Celsius formula with the 273.15 kelvin offset gives the equivalent formula K = (°F + 459.67) × 5/9. Ordinary temperature conversion on the stated Celsius/Fahrenheit/Kelvin basis, subject to its supported lower bound and output range.

Example

Worked example: Fahrenheit = 32. Result: 273.15 K.

Practical tip

The implementation uses the equivalent formula (°F + 459.67) × 5/9 so the supported absolute-zero boundary gives zero directly.
