Fahrenheit to Kelvin Converter
Use this page to convert fahrenheit values into kelvin, with background details, formulas, a worked example, and a quick conversion table.
Conversion formula
This conversion uses an offset formula rather than a single multiplier because the temperature scales start from different zero points.
deg F to K: Apply the scale formula and then add or remove the required offset.
Example: 25 deg F = 269.261111111111 K
Fahrenheit
Fahrenheit is related to Celsius through the formula (F - 32) x 5/9 = C.
History: Daniel Gabriel Fahrenheit introduced the scale in the early eighteenth century.
Current use: Fahrenheit is common for weather, cooking, and consumer contexts in the United States.
Also written as deg F, °F, F, degF, degree F, degrees F, degree Fahrenheit, degrees Fahrenheit.
Kelvin
Kelvin uses the same interval size as Celsius, with absolute zero at 0 K.
History: It was developed for thermodynamics and later integrated into the SI system.
Current use: Kelvin is used in science, engineering, and color temperature references.
Also written as K, kelvins.

Frequently asked questions
What is 0 Fahrenheit in Kelvin?
0 Fahrenheit equals 255.372222222222 Kelvin.
What is 100 Fahrenheit in Kelvin?
100 Fahrenheit equals 310.927777777778 Kelvin.
Why does Fahrenheit to Kelvin conversion need more than a multiplier?
Temperature scales like Fahrenheit and Kelvin start from different zero points, so the conversion uses both a scale factor and an offset.
