Yes and this just goes to prove the metric system IS easier to deal with: no worrying about different miles or gallons or anything else. This cuts down on math errors in things like engineering calculations because you're dealing with less variation in the constants.
The argument against metric is like someone saying we should be using old coal fired locomotives for trains instead of more efficient diesel electrics, because they work and we don't need the extra power or efficiency...
From what I could gather the main reason for us changing over to metric was because most of our trading partners in the world were on that system. That's fine, so we need a handful of people who can talk metric, but it's no excuse to tear up all the charts and tables and make every last citizen learn metric, no to mention resizing all tools etc. What's happened is instead of us being on a single system we are now straddling two systems.
