Formula: K = (°F − 32) × 5/9 + 273.15

How to convert Fahrenheit to Kelvin

To convert Fahrenheit to Kelvin, subtract 32, multiply by 5/9, then add 273.15. Formula: K = (°F − 32) × 0.5556 + 273.15. For example, 32°F = (32 − 32) × 0.5556 + 273.15 = 273.15 K.

Going the other way — to convert Kelvin to Fahrenheit — subtract 273.15, multiply by 9/5, then add 32.

0 K = absolute zero = −459.67°F. Kelvin is the SI unit of temperature used in science and engineering. Fahrenheit is used primarily in the US for everyday temperature measurement.
