Should the U.S. go to the metric system? The metric system is what I grew up on, well sorta. We grew up on "standic." Distance we certainly used metric, centimetres, kilometres, etc. Temperatures were always given in metric, 30C is a fairly hot day, zero is freezing and boiling is 100. Pretty basic, visual, simple and tangible in a way. Mass measurements were sometimes in metric, litres for liquid was widely used and food was sometimes sold per 100 grams. However, when we measured ourselves it was pounds for weight and it was in feet and inches for height. Shoe sizes were also in "U.S. standard." Now, I've been away from Canada for more almost 20 years so maybe that has changed as well?
