Sadly, I was of the era where THE USA IS GOING METRIC.
I learned kilometers next to miles, inches next to centimeters, all of the conversion algorithms. Metric was taught, advocated – it was DEFINITELY finally gonna happen.
That’s when I was 10. Somewhere around the age of 14, all that disappeared. Metric started vanishing from most textbooks. Imperial was re-asserted and “won”.
I blame Congress.
