How to convert Kelvin to Fahrenheit

Temperature scales have different zero points, so you can't just multiply: there's an offset too.

°F = K × 9/5 − 459.67

Example: 300 K = 80.33 °F. Water freezes at 273.15 K and boils at 373.15 K.

About the kelvin and the degree Fahrenheit

Kelvin (K)

The kelvin is the SI base unit of temperature. 0 K is absolute zero; a change of 1 K equals a change of 1 °C.

Degree Fahrenheit (°F)

Daniel Gabriel Fahrenheit proposed his scale in 1724. Water freezes at 32 °F and boils at 212 °F. The US is the main country that still uses it day to day.
