Convert Degrees Fahrenheit to kelvin
1 degree Fahrenheit = 255.93 kelvin · K = (°F − 32) × 5/9 + 273.15
When you need this conversion
This conversion goes from degrees Fahrenheit, the temperature scale used in the US, to kelvin, the SI absolute temperature scale starting at absolute zero. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.
