Re: Agree
I agree with Lord Howe's basic assertion: that the UK's current system of using both Imperial and metric is just stupid. It makes far more sense to standardise. You get the benefits of much easier calculations for a start. No need to remember how many barleycorns* to the foot, for one thing. Everywhere else except the UK and the US uses the Metric system. Yes, it was popularised by the French—although first proposed by a >Briton, so you don't get to use the nationalist card.
The Imperial yard and the Metric metre are so similar, many road signs have been positioned at the equivalent distance in metres, not yards, specifically with a view to easy conversion to metric.
Nobody's suggesting replacing every existing road sign right away either: you can just slap vinyl stickers over the existing signs to update the numbers and units. Everything else stays the same. All you need is a printer who can print adhesive vinyl stickers, and those aren't particularly hard to find. They're not even all that expensive: given the quantities you'd be ordering, and the bulk discounts the printing firms would offer—there's plenty of competition too—you could probably do London's signs for about £200K or so. Not free, certainly, but it'll keep some people in gainful employment. That's quite a good thing to do during a period of recession.
Yes, you'd see a lot of signs saying "Charing Cross 1600 mt." instead of "Charing Cross 1 m", but it's still metric and the actual distance hasn't changed. It's a damned sight cheaper than the typical "Can't Do" attitude of folks here who seem to believe every single sign in the country would need to be re-sited right away for some unexplained reason.
There's nothing in UK law that requires every sign to be exactly a multiple of 1680 yards, or 1000 metres, from whatever they're pointing at. They're only there to tell you how far away something is. You can move them about later, during ordinary road maintenance cycles, when you'd have had to spend the money on replacing the signs anyway.
See? Not difficult, is it?
As for the whole "pints vs. litres" bollocks... please! If you can understand litres of petrol, why can't you understand beer sold in litres too? Instead of asking for a pint, you'd ask for a "half". Instead of asking for a half-pint, you'd ask for "a quarter". Not rocket science, is it?
And, yes, unscrupulous pub landlords and supermarkets will doubtless not drop their prices slightly to take account of the changes, but so what? Inflation and taxes will have wiped out any differences in very short order anyway; this is an utter non-argument.
There are very good reasons for switching to the Metric system. There are no good reasons whatsoever for sticking with two inconsistent systems, one of which, like Microsoft Word's file format, isn't even consistent with itself.
If you're against full metrification because of the "we manage today with the existing complexity and inconsistencies", you cannot possibly have any problem with merely having to cope with bigger numbers on some signs, and ever-so-slightly-smaller beer glasses.
The French, Germans and Italians have been using the Metric system for generations. It's not hard. It's incredibly easy. That's the whole bloody point of it!
