Fahrenheit (°F)
The Fahrenheit scale places the freezing point of water at 32° and the boiling point at 212° at standard pressure.
Fahrenheit is used for weather, cooking, and indoor thermostat settings in the United States and a few other regions.

How to convert
Exact offset formulas in both directions, plus a worked example.
K = (°F − 32) × 5/9 + 273.15
°F = (K − 273.15) × 9/5 + 32
Convert Fahrenheit to Celsius, then add 273.15 for kelvin.
Convert kelvin to Celsius, then apply the °C to °F formula.
Example: convert 98.6 °F to K
98.6 °F → 310.15 K (fahrenheit to kelvin)
About these units
Short background on the units used in this conversion.
Kelvin (K)
The kelvin is the SI base unit of thermodynamic temperature, with 0 K at absolute zero and increments the same size as one Celsius degree.
Kelvin appears in physics, chemistry, and engineering wherever absolute temperature is required.
Frequently asked questions
How do I convert fahrenheit to kelvin?
Convert Fahrenheit to Celsius, then add 273.15 for kelvin. The formula is
K = (°F − 32) × 5/9 + 273.15.What is a useful reference point?
32 °F equals 273.15 K (for example, water freezes at 0°C = 32°F = 273.15 K).
