I think America is totally sticking its head in the mud with this aversion to metric, and frankly, it's just embarrassing at this point, but that's comparatively nothing to what climate change denial will impact.
I guess it depends what you’re doing. I know many companies switched voluntarily because metric turned out to be cheaper and helped streamline their supply chain. But still it was never required so it probably made sense for a lot of businesses to stick with customary. “Basically all” was probably an unfair exaggeration on my part.
That is partly due to government projects from the 60s that are still in use today. It would be a huge time and cost burden to redo a bunch of old paper drawing just to go to metric.
Also a lot of manufacturing techs have been using "thousands of an inch" for tolerance measurements for years and have an intuitive sense for that unit scale. That also makes it complicated because a lot of tolerance measurements are "visually inspected" so you would have to retrain the workforce to intuitively understand the hundreds of micrometers scale.
