Some of us might even opine that the sorry mess could best be corrected by going back to slugs and poundals ..... real units with some meat to them ...
It's relatively unimportant which standard is used. The key thing is that everyone uses the same one.
Since almost every country has adopted SI units, and the great majority of the world's population are taught in them, surely it is time that a great international industry fell into line. Not for the sake of appearance, but because of the undoubted benefits of efficiency and safety that will follow.
My original question is still unanswered - is the 787 really being designed in inches?
