I don’t dispute what you’re saying but I don’t think you are correct (so in fact I do dispute it, sorry). It’s fine for length; great, in fact, and I would go as far as to say good, but when you factor in volume it’s not a debate.

And this is what I’m getting at. I don’t want you to change - you get to choose! - but why is it such a big deal? Imperial is somehow American (whilst of course being English, as you point out, or more properly British, correct me if I’m wrong), but why?

Is it some kind of fear of/animosity to the non-American world? Or the tacit admission that America is perhaps definitively wrong or inferior regarding something? Or maybe there is some global trade reason would fling the door open to foreign 100mm plastic cheese that the US would otherwise be protected from?

Apologies for the cheese dig.

My instinct tells me it is something to do with the latter though.
