About the fahrenheit to kelvin conversion
The fahrenheit (°F) and the kelvin (K) are both units of temperature. Convert between temperature scales — Celsius, Fahrenheit and Kelvin.
Unlike length or weight conversions, temperature scales have different zero points, so the conversion is not a simple multiplication — the converter uses the exact offset-and-scale formula automatically.

Frequently asked questions
- How many kelvin is 1 fahrenheit?
- 1 Fahrenheit equals 255.9278 Kelvin. To go the other way, 1 Kelvin equals -457.87 Fahrenheit.
- What's the formula to convert fahrenheit to kelvin?
- Temperature scales are offset and scaled differently, so there's no single multiplier. The converter above uses the exact formula for each pair.
- Does this converter handle decimals and very large numbers?
- Yes. Type any real number, including decimals or values in the trillions. Math runs entirely in your browser — no server round-trip, no sign-up, and nothing to install.
