1 K = -457.87 °Fone kelvin in degrees Fahrenheit
1 °F ≈ 255.9277778 Kone degree Fahrenheit in kelvins
Kelvin (K): SI base unit of thermodynamic temperature, defined by fixing the Boltzmann constant k = 1.380649e-23 J/K.
Degree Fahrenheit (°F): 5/9 of a kelvin; 0 °F is exactly 459.67 °R above absolute zero, so K = (°F + 459.67) × 5/9.

How to convert kelvins to degrees Fahrenheit
To convert kelvins to degrees Fahrenheit, multiply by 1.8, then subtract 459.67.
Formula
°F = K × 1.8 − 459.67
Examples
- 0 K = 0 × 1.8 − 459.67 = -459.67 °F
- 273.15 K = 273.15 × 1.8 − 459.67 = 32 °F
- 300 K = 300 × 1.8 − 459.67 = 80.33 °F
