How to convert kelvins to degrees Fahrenheit
To convert kelvins (K) to degrees Fahrenheit (°F), multiply by 9/5, then subtract 459.67.
°F = K × 9/5 − 459.67
Example: 300 K = 80.33 °F.
You can also type 300 K to °F into the smart calculator, or mix units: 1 K + 1 °F.

About the units
Kelvin (K)
The SI base unit of temperature. Zero kelvin is absolute zero; the step size matches the Celsius degree.
Degree Fahrenheit (°F)
Water freezes at 32 °F and boils at 212 °F at sea level. Used for everyday temperatures in the US.
Temperature scales do not share a zero, so converting between them needs an offset as well as a factor. Water freezes at 0 °C, 32 °F and 273.15 K. A change of one degree Celsius equals a change of one kelvin and 1.8 degrees Fahrenheit.
