How to convert degrees Fahrenheit to kelvins
Formula: K = (°F + 459.67) ÷ 1.8
Worked example: 68 °F → (68 + 459.67) ÷ 1.8 = 293.15 K
Add 459.67 to the Fahrenheit value, then divide by 1.8. The Fahrenheit scale reaches absolute zero at −459.67 °F, which is 0 K.

What is a degree Fahrenheit?
On the Fahrenheit scale, water freezes at 32 °F and boils at 212 °F, so 180 degrees separate the two points instead of 100. The United States uses it for weather, ovens and body temperature, where 98.6 °F is the classic normal value.
What is a kelvin?
The kelvin is the SI unit of temperature. Its zero is absolute zero, the coldest possible temperature, and its steps are the same size as Celsius degrees, so 0 °C is 273.15 K. It is written without a degree sign and is used in physics, lighting color temperature and astronomy.
