Was it a success though? Given how long it took to transition even in France, it sounds pretty expensive. Given that the rest of Europe wouldn't have bothered with it if the French hadn't gone on a crazy conquering spree, it sounds pretty expensive. Given that the imperial system actual works pretty fine for those who use it, and given that we are stuck with lots of discordant units of measure anyway, and new ones are being invented every day, it doesn't look like the gain was with the cost.
