How to convert fahrenheit to kelvin

The conversion from Fahrenheit to Kelvin uses the formula below. Unlike length or weight, temperature scales don’t share a zero point, so you can’t just multiply.

Formula

K = °F (− 32) × 5/9 + 273.15

For example:

→5 °F = 258.15 K
→100 °F = 310.928 K

Quick reference

▸1 °F = 255.928 K
▸1 K = -457.87 °F
