* Kelvin is an absolute temperature scale. It starts at absolute zero, the point where all molecular motion theoretically stops.
* Fahrenheit is a relative temperature scale. It's based on the freezing and boiling points of water.
To convert between Kelvin and Fahrenheit, you need a formula:
* Kelvin to Fahrenheit: °F = (°K × 9/5) - 459.67
* Fahrenheit to Kelvin: °K = (°F + 459.67) × 5/9
Therefore, a change of 1 degree Kelvin is equivalent to a change of 1.8 degrees Fahrenheit.
However, you can't say "1 degree Kelvin is equal to -458.67 degrees Fahrenheit" because that would imply they are the same temperature, which isn't accurate.
