It would be a pain to make the switch right now. Imagine all the mistakes and problems that would be made during the transition of miscalculating literally billions of physical and digital hand-drawn or scanned in documents.This would in turn delay production and significantly increase costs of doing business. The only practical way I see a transition to metric actually happening is when the majority of our documents and drawings are completely digital using open file formats designed to be able to switch to metric at a future date. The bottom line is people need to be comfortable with the meter. Solution: Put meters next to feet on height strips at gas stations.
