Interestingly it has a dimension correction for temp, however, it doesn't indicate the temp..

9/32in/ft on a 2 foot rule

Very cool, shrink rulers. I've seen a several for sale in the past couple/few months on an "old tool" sales group that I frequent. They are very interesting, although I suspect I'm unlikely to ever come up with a good reason to use one. Best thing that I could think of today would be if I could give someone one to use for a specific project on April 1st.
