Fahrenheit to Kelvin Converter
Convert fahrenheit to kelvin using the formula K = (°F - 32) × 5/9 + 273.15. The calculator below shows higher precision results. The reference table is rounded for readability.
Formula and Step-by-Step
K = (°F - 32) × 5/9 + 273.15
Step-by-step: 1 °F to K
- Start with 1°F
- Convert to Celsius: (1 - 32) × 5/9 = -17.22°C
- Add 273.15: -17.22 + 273.15 = 255.93
- Result: 1°F = 255.93 K

What Are Fahrenheit and Kelvin?
What is a Fahrenheit?
Fahrenheit is a temperature scale where 32 degrees is the freezing point of water and 212 degrees is the boiling point. It is primarily used in the United States.
What is a Kelvin?
Kelvin is the SI base unit of temperature. It starts at absolute zero (the coldest possible temperature) and uses the same degree size as Celsius. 0 K = -273.15 degrees C.
Why convert fahrenheit to kelvin?
People typically convert fahrenheit to kelvin when converting US temperature readings to the absolute scale used in science.
Frequently Asked Questions
1 fahrenheit equals 255.93 kelvin. This uses the formula: K = (°F - 32) × 5/9 + 273.15.
The formula is: K = (°F - 32) × 5/9 + 273.15. See the °F to K formula page for step-by-step worked examples.
Use the kelvin to fahrenheit converter. 1 K = -457.87 °F.
Most unit conversions use simple multiplication because the scales share a zero point. Temperature scales have different zero points (0 degrees C = 32 degrees F), so the formulas require both multiplication and addition or subtraction.
For Celsius to Fahrenheit, double the value and add 30. For Fahrenheit to Celsius, subtract 30 and halve. These give close approximations for everyday use.
