    Oh, and while you are at it, rip out the tachometers from your car and replace them with tachs calibrated in the metric unit of rotation, radians per second. And, I almost forgot, your speedometer has to go because "kilometers per hour" is not a metric unit of speed since "hours" do not exist in the metric system, only "seconds." You need  a speedo marked in meters per second. Oh, another thing, we have to pick up all of our railroad tracks (and we have more that the rest of the world combined) and change them to the metric gauge for railroad tracks which will, of course, mean repacing all of our rolling stock too. Yep, America (you know, the country that put man on the moon) should definately go metric.
