How to convert kelvins to degrees Fahrenheit
Temperature scales have different zero points, so the conversion multiplies and then adds an offset:
°F = K × 1.8 − 459.67
K = (°F + 459.67) ÷ 1.8
Example: 0 K → 0 × 1.8 − 459.67 = -459.67 °F.
Everyday values
| Kelvins | Degrees Fahrenheit | For example |
|---|---|---|
| 0 K | -459.67 °F | absolute zero |
| 255.37 K | -0.004 °F | 0 °F |
| 273.15 K | 32 °F | water freezes |
| 310.15 K | 98.6 °F | body temperature |
| 373.15 K | 212 °F | water boils |
When you need this conversion
Absolute zero, 0 K, is −459.67 °F. The kelvin and Celsius degrees are the same size, while a Fahrenheit degree is 5/9 of that size, so the conversion multiplies by 1.8 as well as shifting the zero point.

About the units
- Kelvin (K): the SI base unit of temperature, starting at absolute zero.
- Degree Fahrenheit (°F): a scale on which water freezes at 32° and boils at 212° at sea level.
Both are units of temperature. The conversion factor comes from the exact definitions above.
