James Clerk Maxwell gets mad about widespread adoption of the Rankine scale, in light of Rankine's initial opposition to Maxwell's theories. They wage a war of words for a few months in leading publications, scientific and otherwise, and this becomes good material for a paragraph long blurb in one of those history-of-science popular books that you see from time to time. Also, one day, a NASA engineer or somebody forgets to convert Rankine to Fahrenheit or something like that and a space probe crashes into Mars instead of going into the intended orbit. Otherwise, I got nothin'.
