Fahrenheit to Kelvin Converter
Convert Fahrenheit to Kelvin instantly. Enter a temperature and get the exact Kelvin value, with the formula and a reference table.
How to convert Fahrenheit to Kelvin
K = (°F − 32) × 5/9 + 273.15
Celsius, Fahrenheit and Kelvin are three temperature scales with different zero points and step sizes, so converting between them means shifting and rescaling — not just multiplying. This tool applies the exact Fahrenheit-to-Kelvin formula, so results are accurate to the decimal.
10 Fahrenheit = 260.93 Kelvin. Multiply your Fahrenheit figure by the factor above (or just type it into the box) to convert any amount.

Frequently asked questions
How do you convert Fahrenheit to Kelvin?
Use the formula K = (°F − 32) × 5/9 + 273.15. Type a value into the box above and the converted temperature appears instantly.
What is a common reference point?
Water freezes at 0°C / 32°F / 273.15 K and boils at 100°C / 212°F / 373.15 K at sea level — handy anchors to sanity-check any conversion.
Why isn't it a simple multiplication?
Because the scales don't share a zero. Fahrenheit's zero and Celsius's zero are different temperatures, so you shift as well as scale.
