The conversion factor of degrees absolutely zero from °F to °K is?

The conversion factor from degrees Fahrenheit (°F) to Kelvin (K) is 5/9.

To convert from Fahrenheit to Kelvin, you can use the formula:
T(K) = (T(°F) + 459.67) x 5/9

So, to convert absolute zero in Fahrenheit to Kelvin:
T(K) = (0 + 459.67) x 5/9
T(K) = 459.67 x 5/9
T(K) = 255.37 K

Therefore, the conversion factor from degrees Fahrenheit to Kelvin is 5/9.
