There was a push back in the 90s to adopt the metric system in California (at Caltrans). They ran into issues because the life of some projects is so long; 10 years or more, and they were using both systems in design and at construction. It was too cumbersome to have state employees and contractors switching between the two systems. And then you'd have someone convert between feet and meters and use the international foot instead of the US Survey foot and have to redesign everything. It was just too easy for a dishonest contractor to find and create backcharges, so they just went back to US Survey feet. And I was left with a bunch of bright shiny almost new and worthless (to me) metric tape measures.
