Frequently asked questions
What is 1 fahrenheit in kelvin?
1 fahrenheit is 255.92777778 K. Temperature scales have different zero points, so you cannot multiply by that figure for other values. Use K = (°F − 32) × 5/9 + 273.15 instead.
How do I convert fahrenheit to kelvin?
Use K = (°F − 32) × 5/9 + 273.15. For example, 37 fahrenheit gives 275.92777778 K. Enter your own value above and the converter does the arithmetic for you.
How do I convert kelvin back to fahrenheit?
Use the Kelvin to Fahrenheit converter, or invert the factor by dividing instead of multiplying.
Is this conversion exact?
Temperature scales differ by an offset as well as a ratio, which is why you cannot convert them by multiplying alone.
