Kelvin to Fahrenheit Formula
°F = (K − 273.15) × 9/5 + 32 (K = (°F − 32) × 5/9 + 273.15)
Water boils at 373.15 K (212 °F). Kelvin values convert cleanly because both scales share the same degree size as Celsius.

About Kelvin and Fahrenheit
Kelvin is the absolute temperature scale starting at absolute zero (0 K = −273.15 °C). The SI unit used in physics and engineering.
Fahrenheit sets 32° at water's freezing point and 212° at boiling. The customary scale for weather and cooking in the United States.
Frequently Asked Questions
What is the formula to convert kelvin to fahrenheit?
°F = (K − 273.15) × 9/5 + 32. To convert back, use K = (°F − 32) × 5/9 + 273.15.
273.15 K = 32 °F — 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 kelvin and fahrenheit start at different zero points. Water boils at 373.15 K (212 °F). Kelvin values convert cleanly because both scales share the same degree size as Celsius.
Where is kelvin-to-fahrenheit conversion used?
