I have always found it a puzzlement that we haven't switched to metric in the U.S, also recalling being taught the Metric System in the '70's and being told we were going to switch. I HATE goofy, goofy things like 5/8ths wrenches. But we buy pop in two litre bottles. "Not quite" Twelve gallons of gas for my (metric) Toyota Prius. Why not just call it 25 litres and be done with it? There IS a switch on my dash that converts the speedometer to kilometres.. Helpful when driving in Canada...but alas, the odometer can't be switched from miles. Ugggh. Pounds and Fahrenheit? Goofy concepts, for sure! But Nautical Miles "seem" to make sense, when you figure it into the degrees of a circle in regards to degrees of Latitude. But then again, we have Daylight Savings time, and I am sure in spite of it, Greenwich NEVER gets closer to, or further away from us just because it's Winter. Or Summer.
Maybe we should go with Coordinated Swatch Time!
