> * Tooling that exists in standard units seems to be a bit of a red herring: I dislike having to own wrenches in both standard and metric units - a transition to one set would actually be nice. At a larger scale, i.e. manufacturing, it would make sense to start replacing things with metric on regular maintenance cycles. With very long cycle things just having a label change. I don't think you'll get rid of that second set of sockets/wrenches for decades. There are going to be just too many instances where there is an old connector, nut, bolt, etc. that needs to be worked with. I think of it as having two sets of wrenches or am buying two sets of wrenches anyway. The metric and imperial sockets come in one set and share the ratchets.
