Greetings Stevedore:
As an expat (U.K.) I know how confusing metric vs. Imperial measurements can be.
I suggest you contact Rodney Walker CEO of FEDESSA at 44.1270.623150.
Rodney.Walker@fedessa.org. for the European and U.K. information.
Contact Michael Homan, managing director for Steel Storage Europe Ltd, a U.K branch of Steel Storage Group based in Australia for the down-under measurements.
Hope this helps. Let me know how you get on. ISS U.K./Europe is coming up in November and I am always looking for good story sources.
