How to convert kelvin to degrees Fahrenheit
The two scales have different zero points, so you need a formula rather than a single factor:
°F = (K − 273.15) × 9/5 + 32
Examples
- (0 − 273.15) × 9/5 + 32 = −459.67 °F
- (273.15 − 273.15) × 9/5 + 32 = 32 °F
- (300 − 273.15) × 9/5 + 32 = 80.33 °F

What is a kelvin?
The kelvin is the SI unit of temperature. It starts at absolute zero (0 K = −273.15 °C) and uses the same step size as Celsius.
What is a degree Fahrenheit?
The Fahrenheit scale puts water's freezing point at 32 °F and boiling point at 212 °F. It is mainly used in the US.
