Road signs get repainted all the time anyway. There is no reason that stuff couldn't be done gradually. The education system has been out front on the issue and teaching both systems for years, so only teaching metrics is actually easier. I had metrics all through grade school. What was wrong with your school.
There is no reason to learn any sort of conVersions anyway. You don't need to know how many miles in a kilometer, you only need to know how many kilometers to your destination.
I am not saying it wouldn't cost some money, but most of the costs could be done gradually and would have been spent as normal upkeep anyway, and the general increase in efficency would more than make up for it in a very short amount of time.
