Thanks Moya, you made me laugh a few times there.

Metrication started in earnest while I was in junior school, so I'm fairly happy with feet and inches too. But if you have to juggle fractions all the time, it feels deeply unnecessary and irksome when there's an alternative - something which engineers have acknowledged long since (in America too) by using tenths and thousandths of an inch. A lot of the time I find myself switching between the two, visualising in Imperial and measuring in Metric. So if someone wants a 1500mm sideboard I'd think "five foot", order the timber which is sold in Metric sizes but which are universally referred to by their equivalent in inches, and then start working in millimetres again. By the way, I rather like non-standard paper sizes because it makes a change to use foolscap or US letter format once in a while.
Incidentally Moya, how is beer sold in Australia? It is inconceivable that Britain will ever abandon the Imperial pint for that purpose!
