We are not “mired” in anything - or “clinging” to anything. You sound like Obama - referring to us as “bitter clingers”.
Using your logic, why are other nations still clinging to their languages - the entire world should just get over it and speak English.
The answer is that they don’t want to lose their culture - they don’t want to be assimilated into a globalist society run by the UN.
There is nothing wrong with our units of measure - they are just parts of our language. Yes, a foot is arbitrary, but so is a meter.
I can convert as fast as you can - and apparently I am better at dividing by twelve and eight - but you are missing the point; I don’t want our culture to be assimilated by the globalists.
Yes, it’s a small thing - but small things will be the death of us - like the proverbial boiled frog.
And by the way, the frog will die sooner under the metric system, since it takes fewer Celsius degrees to reach the boiling point.
/the US is certainly mired in a dual system. I have hundreds of end wrenches in my workshop, some are SAE, some are Metric, and even some are Whitworth. Yet I still occasionally find some fasteners that cannot be fitted properly. It happened just yesterday. I have a friend who nearly caused a fatal accident. He was in charge of an automobile test that spun out of control, ran across a grassy area, and spun into a parking area. Fortunately, no one was hurt. He had told the tester to "drive it at 100", meaning kilometers per hour, and the tester drove it "at 100"...miles per hour. As for language, English has already become the business language of most of the world. You can see traffic signs in English, even throughout China. How many Chinese signs do you see in the US? And, by the way, it takes just as much time to boil a frog regardless of what kind of thermometer you use...And a meter wasn't arbitrary. It was intended to be 1/10,000,000 of the distance from the North Pole to the Equator.
...it takes fewer Celsius degrees to reach the boiling point.
Please, please, please tell me you are joking.
English is a far less logical language than say Latin or Polish or Sanskrit. French is illogical like English
