How to convert kelvins to degrees Fahrenheit
°F = K × 1.8 − 459.67
°F = K × 1.8 − 459.67, exactly (rearranged from NIST SP 811 B.9: T/K = (t/°F + 459.67)/1.8).
Examples
- 63.14 K = -346.018 °F: Triple point of nitrogen (NIST Chemistry WebBook) (NIST)
- 310.15 K = 98.6 °F: Average normal body temperature, expressed in kelvin (MedlinePlus (NIH))
Kelvin to fahrenheit chart
| Kelvins (K) | Degrees Fahrenheit (°F) |

Common mistakes
- A 1 K change equals a 1.8 °F change. Apply the 459.67 offset only to absolute temperatures, not to differences.
