About Kelvin to Fahrenheit Conversion
Converting between Kelvin and Fahrenheit is a common task in scientific and academic contexts. Our Kelvin to Fahrenheit Converter makes this process simple and accurate.
Conversion Formula
The formula to convert Kelvin to Fahrenheit is:
°F = (K – 273.15) × 9/5 + 32
This formula takes the temperature in Kelvin, subtracts 273.15 (to convert to Celsius), multiplies by 9/5, and then adds 32 to get the equivalent temperature in Fahrenheit.
Understanding Kelvin and Fahrenheit
The Kelvin and Fahrenheit scales are two different ways of measuring temperature:
- Kelvin (K): The SI unit of temperature used in scientific applications. The Kelvin scale starts at absolute zero (0K), which is the theoretical temperature at which all thermal motion ceases. There are no negative temperatures in the Kelvin scale.
- Fahrenheit (°F): Primarily used in the United States for everyday temperature measurements. In the Fahrenheit scale, water freezes at 32°F and boils at 212°F at standard atmospheric pressure.
Note that the Kelvin scale does not use the degree symbol (°). Temperatures are expressed simply as “K” rather than “°K”.

Frequently Asked Questions
What is the difference between Kelvin and Fahrenheit?
Kelvin and Fahrenheit are different temperature scales with different reference points. Kelvin is the SI unit used in scientific contexts and starts at absolute zero, while Fahrenheit is primarily used in the US for everyday measurements. In Kelvin, water freezes at 273.15K and boils at 373.15K, while in Fahrenheit, water freezes at 32°F and boils at 212°F.
What is absolute zero in Kelvin and Fahrenheit?
Absolute zero is 0 Kelvin, which equals -459.67°F. This is the theoretical temperature at which all molecular motion stops.
Why doesn’t Kelvin use the degree symbol?
Kelvin doesn’t use the degree symbol (°) because it’s an absolute temperature scale based on absolute zero, not an arbitrary point like the Celsius and Fahrenheit scales. It’s simply written as “K” rather than “°K”.
Is there a temperature where Kelvin equals Fahrenheit?
No, there is no temperature where Kelvin equals Fahrenheit. The scales have different zero points and different increments, so they never intersect at the same numerical value.
