Sure, it starts with roundabouts, but the next thing you know we’re using the metric system. It’s a slippery slope. My family left Europe for a reason.
I have no idea without looking it up how many yards, or feet are in a Mile. I do know that a foot is 12 inches, or 30 centimeter (cm)
BTW, I doubt very much that was the reason your ancestors left Europe.
I was taught the metric system in during 3rd grade in the 70’s because America was going to be all metric before 1980.
I wish it would have taken hold. The Metric system is by far superior and the way God intended measurements to work.
