How to convert Fahrenheit to Kelvin
Temperature scales have different zero points, so you can't just multiply: there's an offset too.
K = (°F + 459.67) × 5/9
Example: 350 °F = 449.82 K. Water freezes at 32 °F and boils at 212 °F.
About the degree Fahrenheit and the kelvin
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.
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.
