Did you know that the US is one of only three countries that have not adopted the metric system? Myanmar and Liberia are the other two. What are we waiting for? It's too expensive? Too much of a hassle?
How much of our kids' education is wasted on learning standard units? Three teaspoons per tablespoon, 16 tablespoons per cup, two cups per pint, two pints per quart, four quarts per gallon. How much extra ink is wasted printing two measurements? Or if they don't, then they're printing two kinds of labels, and storing separately packaged product for export to, oh, anywhere. How much waste is there in that? How many factories have to make things in standard and metric? Wasteful. And when someone screws up converting? Or when someone brain farts and uses the wrong system, as was the case with the Mars Climate Orbiter? There was a $150 million that could've gone to metric education and adoption!
Every time I add up my veggie weight, and I do it in ounces, I have to add up all the ounces, divide by 16, write that number off to the side to save for when I add up the pounds, take the remaining decimal, multiply it by 16 to get the remaining ounces, and then add up the pounds. And that's just for weight.
What a frickin' headache. From now on, it'll all be done in metric.
