The metric system is far superior to the bizarre system of feet, miles, pounds, and gallons used in the United States. The whole rest of the world seems to get this. So why aren’t we doing it, too?

The reasons to go metric are stronger than ever, and it’s time to revive the effort. In our increasingly global economy, America’s bizarre measurement system puts the country at a disadvantage. Popular opinion on the matter seems to be quite positive, and there are some hints of change on the horizon.

I lived in the US for many years and grew up in Canada during the switch from Imperial to Metric so I get both systems. There’s no doubt metric is much easier to do calculations with but, even here in Canada, there is still a lot of confusion due to the mashup of the two systems.
