About Fahrenheit to Kelvin Conversion
Converting between Fahrenheit and Kelvin is a common task in scientific and academic contexts. Our Fahrenheit to Kelvin Converter makes this process simple and accurate.
Conversion Formula
The formula to convert Fahrenheit to Kelvin is:
K = (°F – 32) × 5/9 + 273.15
This formula takes the temperature in Fahrenheit, subtracts 32, multiplies by 5/9 (to convert to Celsius), and then adds 273.15 to get the equivalent temperature in Kelvin.
Understanding Fahrenheit and Kelvin
The Fahrenheit and Kelvin scales are two different ways of measuring temperature:
- 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.
- 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.
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 Fahrenheit and Kelvin?
Fahrenheit and Kelvin are different temperature scales with different reference points. Fahrenheit is primarily used in the US for everyday measurements, while Kelvin is the SI unit used in scientific contexts. Kelvin has no negative values as it starts at absolute zero (-459.67°F).
What is absolute zero in Fahrenheit?
Absolute zero, which is 0 Kelvin, is equal to -459.67°F. This is the theoretical temperature at which all molecular motion stops.
Why do scientists use Kelvin instead of Fahrenheit?
Scientists use Kelvin because it’s an absolute temperature scale that starts at absolute zero, making it more suitable for scientific calculations. Additionally, it’s part of the International System of Units (SI), which is the standard measurement system used in science globally.
Is there a temperature where Fahrenheit equals Kelvin?
No, there is no temperature where Fahrenheit equals Kelvin. The scales have different zero points and different increments, so they never intersect at the same numerical value.
