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.

Selected K values converted to °F using the exact offset formulas from this tool.
| K | °F |
|---|---|
| 0 | -459.67 |
| 200 | -99.67 |
| 273.15 | 32 |
| 300 | 80.33 |
| 373.15 | 212 |
How to convert
Exact offset formulas in both directions, plus a worked example.
°F = (K − 273.15) × 9/5 + 32
K = (°F − 32) × 5/9 + 273.15
Convert kelvin to Celsius, then apply the °C to °F formula.
Convert Fahrenheit to Celsius, then add 273.15 for kelvin.
Example: convert 300 K to °F
300 K → 80.33 °F (kelvin to fahrenheit)
About these units
Short background on the units used in this conversion.
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.
Frequently asked questions
How do I convert kelvin to fahrenheit?
Convert kelvin to Celsius, then apply the °C to °F formula. The formula is
°F = (K − 273.15) × 9/5 + 32.What is a useful reference point?
273.15 K equals 32 °F (for example, water freezes at 0°C = 32°F = 273.15 K).
