  • My last project in aerospace with 100’s of people was mostly Imperial. There is a lot of mixing of units and you can basically design your subsystem however you want. There was a mandate decades ago to go metric, but that has largely been ignored. It’s the worst of both worlds!

    My current project is just a couple people, so I mandated all metric. I have to spend a lot of money on tooling, but it is largely fine. I would say 10 years ago getting some fancy aerospace grade fasteners was easier in Imperial, less so today.

    My mind still defaults to Imperial for very small dimensions like a 8 thou gap or something.
