Kelvins to degrees Fahrenheit
°F = (K − 273.15) × 9/5 + 32
Reverse: degrees Fahrenheit to kelvins
How to convert kelvins to degrees Fahrenheit
Temperature scales start from different zero points, so the conversion is not a single multiplication. Use the formula above: °F = (K − 273.15) × 9/5 + 32. For example, 20 k is -423.67 f.
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 degrees Fahrenheit are in a kelvin?
This is a temperature scale, so it depends on the value: use °F = (K − 273.15) × 9/5 + 32.
How do I convert kelvins to degrees Fahrenheit in a spreadsheet?
Put the temperature in A1 and type =(A1-273.15)*9/5+32.
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.
