A Country Mile
Just how
far is a country mile?
The thought came to me as
I stood by my BMW on a corner just north of
Gundaroo.
The road ahead to town had a large
Detour sign blocking the way,
as the bridge was out. The side road was gravel, graded and rolled
for sure, but narrow and slick.
I flicked open the top box
and grabbed the map to help with decision
making, only to have it disappear in a cloud
of dust as a large articulated truck rolled
up on the gravel.
Where are you headed
called the bearded road worker from the cab.
Canberra.
Then head back this
way.
How far on the gravel?
I wavered.
About five ks.
It might as well be a Country Mile
I thought.
And so it turned out to be.
Of course there are times
when real measures matter like the
time I was navigating my mates yacht
across Bass Strait. Then it s a life and death matter frankly. But
other times it really doesnt matter
too much or
does it?
A mile as all
baby-boomers will tell you, straight from
the back of an old 48 page exercise book,
is actually 1760 yards, or 5280 feet or 63,360
inches, but so what? (and
how the hell does that translate into metres
and kilometers, and why the funny numbers
surely we are talking about 1000 yards
in a mile? Nope, that would be just too easy
for the English.
But then there are different
types of miles. The one Im more used to is the nautical
mile which is actually a bit further
than a statute mile or an English
mile. Practically, it is 800 feet further.
And for those who read far too many Hornblower
books, its really about leagues,
one of which is about three sea miles. But
here, there really is some logic in the measurement
of a nautical mile because its actually
one minute of longitude, which is very useful
for navigators. Confused now? Well, if you
circled the equator you would go through 360
degrees as we all know.
Each degree is broken up into 60 minutes
and one of these minutes is equal to one nautical
mile! Simple really! (and
ok, for the real maths fiends that equates
to 21,600 nautical miles around the earth).
But here is the rub. As the
years have passed, we have been able to measure
the circumference of the earth a little better. To be precise, the Americans were not prepared
to let the English own the nautical mile,
and proclaimed it to be slightly longer (of
course) at 6080.20 feet.
Of course it took the French to tell
them that they were all wrong and come up
with the third measure of the nautical mile
at 6076.11594 feet! This is now called the
international nautical mile -
pedants.
So why is this all relevant?
Well if there is such a debate about such
an important measurement as the nautical mile,
does it really matter to we
land lubbers if a land mile is a little more
or a little less?
More importantly, if our
BMW bikes measure everything in kilometers,
who gives a stuff about miles anyway? Well some do, so here it is one mile
equals 1.609344 kilometres and 1 kilometre
equals 0.6213712 miles satisfied? You
will need to know that when you go riding
in the good old US of A.
Ok, so a mile is longer than
a kilometre. So a country mile, to a person for whom time is not such a big issue and distance really not so
important unless they are dying of thirst,
or the tractor has run out of petrol, must
be a bit further.
To be precise;
A
country mile is a little way further than
you would like to walk on a hot day, but not
so far that you couldnt walk it if you
really needed to, or that you might walk to
a pub if it was your first beer in a month,
but definitely longer than a k or a statute
mile. Sometimes
it will be a few kilometers and sometimes
lots, however many that might be, but always
more than you would like when carrying a gerry
full of petrol or a flat tyre.
So on this day, in the dust
north of Gundaroo, a country mile was 5 kilometres
off the lip, but 12.1 kilometres by the gauge
just as you would expect!
But next week when McGrath
is bowling at the English captain, and the
ball whistles past off-stump, the poms will
say there, missed by a country mile!
and then it will be 2.31109856 inches measured
by radar the perfect country
mile dont you think?
