Title: Scientific unit equivalent to insulation R-values

An R-value expressed in scientific units is

		hour * feet * feet * degrees F / BTU

I found this out last weekend at our local library (thus answering my own
query). It was remarkably hard to find (not the library, the answer!).

Several people were kind enough to supply information in response to my query.

	- R = 1/U  ( a U is unit of thermal conductivity rather than insulation)

	- R's are equivalent to inches of wood (this of course varies with the
	  wood used, but according to the table I found it's remarkably close)

	- Bill Brown (cbosgd!cbosg!cwb) sent the unit equivalence, thus
	  independently confirming what I had found. Thanks Bill!


Thanks also for all of you that indicated interest in this.
