Degrees Fahrenheit to kelvins
K = (°F − 32) × 5/9 + 273.15
Reverse: kelvins to degrees Fahrenheit
How to convert degrees Fahrenheit to kelvins
Temperature scales start from different zero points, so the conversion is not a single multiplication. Use the formula above: K = (°F − 32) × 5/9 + 273.15. For example, 20 f is 266.483333 k.
Quick estimate
Work through the formula above for exact results; for weather temperatures, “double and add 30” (°C to °F) or “take 30 and halve” (°F to °C) gets within a few degrees.
Where it comes up
Temperature conversions come up in weather forecasts, cooking and oven settings, body temperature and science classes.

Questions
How many kelvins are in a degree Fahrenheit?
This is a temperature scale, so it depends on the value: use K = (°F − 32) × 5/9 + 273.15.
How do I convert degrees Fahrenheit to kelvins in a spreadsheet?
Put the temperature in A1 and type =(A1-32)*5/9+273.15.
Are the values in the table exact?
They are calculated from the exact definitions of the units and rounded only for display. Open any row for the full working.
