Something's Afoot

The whole foot-kilometer thing. So confusing. First, we were going to transition, and then ... we ... well, we weren't but we kind of were but not really. So now we buy soft drinks in liters but milk by the quart and gallon. We run 10Ks but drive miles. Do they even still teach kilometers and liters in school? And how did it come to this point, anyway, where we're neither here nor there?: http://www.slate.com/articles/technology/books/2014/08/john_marciano_s_whatever_happened_to_the_metric_system_reviewed.html
