I can see it now...
One state decides to change all its signs to metric on a certain stretch of highway, to "integrate" people to the metric system. Before long, the people who actually look at the speed limit signs see 120 km/h, and think "Hell yeah, I can go 120 mph on this interstate." Needless to say, a forced conversion to metric would be counterproductive 😉
All the items that need to metric already are in the US. The pharmacy system has switched entirely to metric. All the sciences use metric.
Isn't it funny though that we sell 12 oz cans of pop, 32 oz drinks in our fast food restaurants, 20 oz bottles in the store, as well as 1 liter, 2 liter, and 3 liter bottles of pop. I think we did a pretty good job of bastardizing the metric system already 😛
Oh, and Dabanshee, I bet you learnt yourself good in them metric schools.
<< Australia changed over from Imperial to metric arround 1974 so I learnt both at school, as I was about 9 then >>
