Fahrenheit to Kelvin Converter °F → K
1 °F equals 255.9277778 K — note this scale uses an offset formula, not simple multiplication. Type a value below — the conversion happens instantly, entirely on your device.
72 °F = 295.37222 K
72 degrees Fahrenheit = 295.37222 kelvins
72 × 0.555556 + 255.372 = 295.37222
These scales have different zero points, so the conversion multiplies by 0.555556 and then shifts by +255.372.
How to convert degrees Fahrenheit to kelvins
K = (°F − 32) × 5/9 + 273.15 — convert to Celsius first, then add 273.15.
Example: 72 °F = 295.372 K.
To convert the other way: °F = (K − 273.15) × 9/5 + 32 — or use the dedicated K to °F converter .

About the units
What is the Fahrenheit scale?
Degrees Fahrenheit (°F) place water’s freezing point at 32° and boiling point at 212°. It is the everyday temperature scale in the United States.
What is the Kelvin scale?
The kelvin (K) is the SI base unit of temperature, starting at absolute zero (0 K = −273.15 °C). A change of 1 K equals a change of 1 °C; kelvins are standard in science and engineering.
Frequently asked questions
