It would be a big task to switch from metric to imperial here if situations were reversed. It would probably cause mental meltdowns and blown fuses plus all kind of production slowdowns. I personally would positively hate it. I always struggle when I am building to US plans with imperial measurements..

Perhaps the process could start with the schools and teachers. The rest would follow from there.. I know that MIT and other institutions have professors and lecturers insisting on SI units in all coursework.
