Fahrenheit to Kelvin Formula
K = (°F − 32) × 5/9 + 273.15 (°F = (K − 273.15) × 9/5 + 32)
Absolute zero is −459.67 °F (0 K). This conversion goes through Celsius internally: Fahrenheit → Celsius → Kelvin.

About Fahrenheit and Kelvin
Fahrenheit sets 32° at water's freezing point and 212° at boiling. The customary scale for weather and cooking in the United States.
Kelvin is the absolute temperature scale starting at absolute zero (0 K = −273.15 °C). The SI unit used in physics and engineering.
Frequently Asked Questions
What is the formula to convert fahrenheit to kelvin?
K = (°F − 32) × 5/9 + 273.15. To convert back, use °F = (K − 273.15) × 9/5 + 32.
32 °F = 273.15 K — how do I convert other values?
Type any value into the converter above; it applies the offset formula automatically, handling the different zero points of the two scales.
Why can't I just multiply to convert temperature?
Because fahrenheit and kelvin start at different zero points. Absolute zero is −459.67 °F (0 K). This conversion goes through Celsius internally: Fahrenheit → Celsius → Kelvin.
Where is fahrenheit-to-kelvin conversion used?
Fahrenheit sets 32° at water's freezing point and 212° at boiling. The customary scale for weather and cooking in the United States. Kelvin is the absolute temperature scale starting at absolute zero (0 K = −273.15 °C). The SI unit used in physics and engineering.
