The Fahrenheit to Kelvin Conversion Calculator is an online tool designed to quickly convert temperatures from Fahrenheit (°F) to Kelvin (K) and vice versa. Ideal for students, scientists, and anyone interested in temperature conversions, this calculator simplifies the process, ensuring accurate results.

Fahrenheit to Kelvin Converter

Convert temperature from Fahrenheit to Kelvin and vice versa.

How to Use

To convert a temperature from Fahrenheit to Kelvin, enter the temperature in Fahrenheit into the first input field. The equivalent temperature in Kelvin will be automatically calculated and displayed in the second field. For conversion from Kelvin to Fahrenheit, enter the Kelvin value, and the Fahrenheit value will be updated. The calculator allows bidirectional conversions and provides instant results.

Conversion Formula

The calculator uses these conversion formulas:

  • To convert °F to K: Kelvin = (Fahrenheit - 32) * 5/9 + 273.15
  • To convert K to °F: Fahrenheit = (Kelvin - 273.15) * 9/5 + 32

Educational Insight

Fahrenheit and Kelvin are two scales used for measuring temperature. Fahrenheit, used mainly in the United States, bases its scale on the freezing and boiling points of water, set at 32°F and 212°F, respectively. Kelvin, part of the International System of Units (SI), starts at absolute zero, the theoretical lowest possible temperature, and is primarily used in scientific contexts. One Kelvin is equal to one degree Celsius, but the Kelvin scale starts at absolute zero (-273.15°C). This calculator bridges the gap between these two temperature scales, making it easy to understand and convert temperatures for various applications.
