The only exception I could think of was R-values, eg, "Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch." , quoting https://en.wikipedia.org/wiki/R-value_(insulation)#Example_values https://en.wikipedia.org/wiki/R-value_(insulation)#Example_v... . From the same source, "an R-value expressed in I-P (inch-pound) units[13] is about 5.68 times larger than when expressed in SI units"; the latter being measured in K⋅m2/W.
