What are fahrenheit and kelvin?
Fahrenheit puts water’s freezing point at 32° and boiling at 212°, and is used mainly in the United States. Kelvin is the SI base unit of temperature, starting at absolute zero (−273.15 °C) with no negative values. For reference: a comfortable room is about 21 °C (70 °F), and normal body temperature is 37 °C (98.6 °F).
How to convert fahrenheit to kelvin
Temperature scales don't share a zero point, so you can't convert by a single multiplier — use the formula K = (°F − 32) × 5/9 + 273.15. For example, 0°F = 255.372K, 37°F = 275.928K, and 100°F = 310.928K.

FAQ
What is the formula to convert fahrenheit to kelvin?
K = (°F − 32) × 5/9 + 273.15. Temperature scales don't share a zero point, so you convert with this formula rather than a single multiplier.
What is 0 °F in K?
0 °F = 255.372 K, and 100 °F = 310.928 K.
Why can't I just multiply fahrenheit by a number?
Because Fahrenheit and Kelvin start counting from different zero points, multiplication alone would give the wrong answer — you also have to shift the scale, which the formula above handles.
