Pretty interesting article. What stood out for me was why the US didn't standardize to metric: They standardized the whole country on something because they had to - too much people from different places came together, each with their own measurement system. The rest of the world standardized later. I assume the overhead from conversion only became unbearable when some level of commerce between different nations was reached. When they standardized, they had better science available. So now there are 2 landmasses, each big and integrated enough to have internal units, not feel too much pain from using a different kind of units. Everything goes reasonably well, unless they meet.
