Being from Germany, I can fully sympathesize with your view.
But then, I have been in many international projects where we had to cater for the US folks
who insist on using inches, feets, and other obscure stuff in their technical specs.
mm/dd/yyyy, anyone? What's the logic behind that order?
Mind you, I don't care if they use it in private life or in local business, we also use
"dozen" or "pound" at our local store. (Though our pound is different than that from the UK
and from the US. :-) I'm also willing to get myself aquianted with that strange Fahrenheit
notion when I'm on the road privately. That's a cultural matter, and then I'm a visitor; I
don't run around with short trousers in islamic countries either.
But in documents of international projects, that's completely different. Here it is a pet
peeve of mine, due to several severe problems that I have experienced first-hand. Metric units
should be a must here (and also date notation in form of YYYY-MM-DD), but try to convince my
fellow US project partners of that. No chance, and it just brings out the label `not
constructive'. :-(
Anyhow, anough rambling, back to work. :-)
