Fast forward 40 or 50 years and of course people have lost fasteners n the course of doing repairs and simply replaced them with regular old metric from the hardware store, thus creating a metric/SAE nightmare. My 69 Datsun Roadster required a complete set of SAE and a complete set of metric to do any sort of work on it.  |
When we switched to Metric in Canada I was in primary school so learned both systems, I primarily think in Imperial but can go back and forth easily. I do remember my dad being really pissed though because they went from selling gas by the gallon to the litre and I don't think they changed the price to compensate, almost 4X more to fill the tank. I get a little screwed up when I go drive to the US, your gallon is smaller than an imperial gallon and then the difference in the dollar. But your booze and beer is cheap so it's all good.
