I got a package from the US of A today.
On the CN22 customs declaration form, surely the most international of documents almost by definition, the weight was printed only in lbs, with no metric equivalent. Now that strikes me as dumb, and it's the sort thing that might, not unreasonably, lead some people to perceive that the US is a teeny weeny bit arrogant about insisting on using weights and measures (in the explicit context of international trade let us remember) that are out of step with the rest of the world.
It's one thing to use whatever units you like in your own backyard, heck it's your backyard, but when talking to the other 96% of the world's population it would at least be only polite to try and speak the same language, units wise.
I suspect that this is what is at the heart of the rabid taking of positions pro and anti the US adopting metric units.
Woman: you left the toilet seat up, again. The only reason I didn't fall in, is because I fell in the toilet, once, when I was 15. I always check, now, before I pee. You're the only man in the house, so you have to respect the female majority.
Man: If it's my job, I have to lift and put down the lid every time I pee. But logically speaking, I might have to use the bathroom again, before any of you do. So I would have done extra work for nothing. You said you always check, anyway. So if the lid happens to be up, then the first woman to use it will have to put it down, and then the women are collectively doing half the work between them, so it will be nothing. There are so many women, that this will be trivial to you. I am the only one that has to lift this damn lid every time I pee, and you all have it easy.
Woman: Ok, then. Why don't you pee sitting down, too? Then all of us will be able to sit down without even looking!
Man: Fine, I'll put the lid back down.
~1 week later, repeat.

Yeah, that is annoying to you, and I apologize for America. But you do at least still read the units. The day we fill out or read the "weight" section as simply "8.4," then we will all be zombies.
Maybe US companies/government offered to use only metric, but this offer was politely declined. Seeing as US is officially imperial, it is maybe something that is negotiated between countries, diplomatically? And maybe this happened 100 years ago, and this is simply the way they have handled it ever since then?
From the EE's perspective, there is also RTFM. I wonder what did the instructions say on the form, if any.
