A degree Kelvin (K) and a degree Fahrenheit (°F) are different units of temperature, and their size comparison can be a bit counterintuitive due to the different scales and intervals used.
The size of one Kelvin degree is equivalent to one degree Celsius (°C) in terms of temperature interval. On the other hand, one degree Fahrenheit (°F) is smaller than a degree Celsius. Specifically, the difference between one degree Fahrenheit is equal to \( \frac{5}{9} \) of a degree Celsius (or Kelvin).
So, to answer your question: a kelvin degree is larger than a Fahrenheit degree.
