A big problem was how they tried to teach it in school.
“A mm is .03937 inches. A cm is .3937 inches. A dm is .3281 feet. A meter is 39.37 inches. A gram is 0.035 ounces. There will be a quiz tomorrow.”
Now, if they’d handed out meter sticks and said, “this is how long a meter is. See how big a cm is?” And then measured things that way, the situation might be a little different. As it was, the cm side of our rulers was something we ignored.
Then there was this machinist guy who was explaining, “it’s impossible to do precision work in the Metric system.” I thought, “anybody ever tell Mercedes that?” Seemed to me a hundredth of a mm would be a really fine measurement.
