But don't forget the Yanks have a different gallon to the UK. 1.2 US
gallons is about 1 UK gallon.

My experience in NI was just the opposite - I reached where I was going
in about 40% less time than I thought it should.
Then I realised that the (all-Ireland) road map I was using was marked

Americans don't rule the world they just think they do. Hollywood has
told them so.

Months are also natural (and imprecise) - weeks and fortnights are
obvious divisions, even if you are not creationist. milli-days seem to be
the most useful SI division of a natural time measurement.
The speed of light in a vacuum is also a natural unit of measurement, if
a little high for normal use. nano-c would be a useful SI division, being
about 0.3 m/s. nano-light-seconds could be a unit of distance, but you
would want a invent a specific name for it.
Or you could use planck length as a 'natural' unit of distance, although
it is delibertaly small. There doesn't seem to be an SI prefix above yotta,
but 10^38 planck lengths are a usable 1616 metres.

Is there any reason why the month is divided into seven days rather than any
other? And is there any reason why a day is divided into 24 hours each of 60
minutes each of 60 seconds - apart from this being the way that it was done
Given that the lunar month is about 28 days, is there scope for having 13
months to match the lunar cycle more accurately? It's a shame that the day,
the lunar cycle and the year don't align so you'd end up with a short 25-day
13th month after your 12 28-day months... Still, it's better to have only
one odd month, rather than a fairly random sequence of 30- and 31-day
