How to convert Kelvin to Fahrenheit
Temperature scales have different zero points, so use the formula °F = (K − 273.15) × 9⁄5 + 32 rather than a multiplier. The table below applies it to common values; for the opposite direction use the Fahrenheit to Kelvin converter.
About these units
Kelvin (K)
The kelvin is the SI unit of temperature, starting at absolute zero (0 K = −273.15 °C). Kelvin steps are the same size as Celsius degrees, and no degree sign is used.
Fahrenheit (°F)
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F, so one Fahrenheit degree is 5/9 of a Celsius degree. It is the everyday scale in the United States.
