What is 0°F in Kelvin?
0°F is 255.4K.
Fahrenheit to Kelvin
Type a temperature to convert it from Fahrenheit to Kelvin. The two scales do not share a zero, so the conversion shifts as well as scales.
Result
Fahrenheit and Kelvin, side by side
Fahrenheit and Kelvin measure the same thing on different scales, and they start counting from different places. That is why the conversion is not a simple multiplication: 0°F comes out as 255.4K, not zero.
Going the other way, 0K is -459.7°F. Any converter that treats this as a ratio gets both directions wrong.
The Fahrenheit scale puts water’s freezing point at 32 °F and its boiling point at 212 °F, so the two sit 180 degrees apart against 100 in Celsius. It is the everyday scale in the United States, where normal body temperature is usually quoted as 98.6 °F.
The kelvin is the base unit of temperature in the International System and starts at absolute zero, the point where no more heat can be taken away. It has no negative values and is written without a degree sign: water freezes at 273.15 K. Science and the color temperature of light bulbs use it.
