5 feet 6.535 inches. Does imperial system warrant a note?. Apparently thats not even the correct term, they're called U.S. customary units. So yeah, add note?
Like the name suggests. An abhorrent measurement like the imperial system should have died when democracies were a present thing. We live on a globalized almost free commerce world now. Things like regional blu-ray, wrong way driving or electric plug/socket voltages should be buried next to the PAL 50Hz system.
