Ahhh......the metric system. To this day the US, Burma (Myanmar) and Liberia are the only nations in the world who have not formally adopted the metric system.
While the US has authorized the use of the metric system since 1866, outside of science and a few other places, it was largely ignored. In 1975, Congress authorized a ten year plan for national conversion. Which seemed like a good idea. Canada and Mexico already adopted it
And PSAs like this began appearing. (I remember watching this - my elementary school teachers were (quite reluctantly) trying to teach it and I tried to explain it to my mom and how nearly every country in the world uses it and now the US was changing over. She rolled her eyes and said with deadpan sarcasm "Wow. And all this time, I thought we won the war.....")
Today you find some uses of the metric system. Namely this:
And along the borders for our Canadian and Mexican friends
|Speed limit sign in Blaine, WA.....just a few meters over the border.......|
So what happened?
Simple, for the most part, we Americans resisted. In fact, the government gave up around 1982 and closed the metric conversion office when then President Reagan made the first sweeping wave of government cutbacks, ending all funding for a national conversion.
However there are still a few hopeful holdouts. But it's doubtful Americans will ever convert.
