I think the country would be ok switching to metric for pretty much all measurements. It would certainly take some time to make the transition and older folks like my parents would remain confused over it, but eventually we'd be able to git r done.
Like CD I actually like the F system for weather temperature, but for me the reason is that it has finer gradients by degree, so each degree between freezing and boiling is almost twice as precise in F than it is in C. Like anything else, we'd get used to it if we switched, but I still like the finer detail of the F system.
