How to convert Kelvin to Fahrenheit

To convert Kelvin to Fahrenheit, subtract 273.15 then multiply by 9/5 and add 32. Formula: °F = (K − 273.15) × 1.8 + 32. For example, 373.15 K = (373.15 − 273.15) × 1.8 + 32 = 212°F.

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

0 K = absolute zero = −459.67°F = −273.15°C. Kelvin is the SI unit of temperature used in science. Fahrenheit is used primarily in the US for everyday temperature measurement.
