Me too, although it was never even started sensibly. Changing a speed
limit from 55 mph to 88 kph made no sense, as far as I'm concerned; it
should have been changed to 60 kph.
That would have been awfully slow (-:
And selling things like milk in .9463 liter bottles instead of 1 liter
bottles made no sense either.
We seem to manage OK with milk: a UK pint is somewhat more than half a
litre, so our milk is sold in one point something litre bottles (2
pints), and has been for some time. And jam (US: jelly) in 454g jars,
and ...
These kinds of things (and there were many others) weren't really
changing to the metric system.
Manufacturers here _are_ gradually switching to rounder numbers, but it
does seem to be taking many decades. I guess the main reason is that
they have machinery in the old Imperial sizes, that refuses to wear out;
partly being wary of being accused of trying to take advantage (some
folk have long memories from when we metricated the currency, about
1970!), and partly "to give customers what they want".
We should change to the metric system primarily because our
measurement system should be the same as the rest of the world's, and
secondarily because the metric system is much easier to do arithmetic
in.
Very true.
As far as I know, the only thing that we use the metric system for is
wine and liquor bottles.
And for those (wine, at least - can't say for liquor), the strange unit
the centilitre (cl) is used, which isn't used anywhere else in the
metric system! (At least, in UK it is.)
And we should also change to using Celsius for temperatures, because
the rest of the world does. Most people seem to think that's part of
the metric system, but I don't.
Well, it is a "centigrade" system - 100 degrees between freezing and
boiling, or at least that was the intention, and is still close enough
to that for practical purposes.
