I assume that the FAHRENHEIT value in the equation is actually
a temperature difference, in degrees fahrenheit, between the
"inside" and "outside."  As I remember, thermal difference is the driving 
force (analagous to voltage difference) in heat transfer problems.
It's in fahrenheit in order to be consistent with BTUs (good old English
units).
