Yup Cyndi it was. From what I understand the last time it was seriously looked at was about 110 years ago. :-) Long before many counties switched over to the metric system. What ever the issues with metric time are they don't impact the system of weight
Andy I agree it does make the math easier but I would suggest that there are actually a few more positives. The big one being global standardization which in itself can be a big time saver. Just ask a project engineer about that. I worked outside of NA on projects and I was often asked when the US was going to go metric so the engineers could save time by not having to recalculate specs from the US. Can't tell you how many hours I have seen wasted when a piece of equipment breaks down in another country and everyone is in place to fix it but its discover the bolt or part is not metric and they have to go off in search of the right tool/part. Funny enough I also avoid buying US published cook books that do not include the ingredients in metric. Takes the fun out of cooking if one has to waste time doing math!
I actually don't have an issue with the US not going metric, I just look at it as one of the big wonders of the world. :-)
