“What is a cubit?”
– Noah (Bill Cosby) to God in Noah’s Ark
Before you start reading, try and
guess (in US or metric terms):
1 furlong = ___________________
1 league = ___________________
1 bushel = ___________________
1 barrel of oil = _______________
1 knot = _____________________
1 stone = ____________________
1 cm3 = 1ml = 1 gram (for water of course) is the single best
reason to use the metric system. Any child with a slightest visual perception
skill can grasp it. Not only that, all divisions are by a measure of 10, so
Roman in its concept. By contrast, the Anglo-Saucon measurement system is a
mathematics student’s nightmare: 2 pints = 1 quart x 4 = one gallon = 16 cups;
12 inches = one foot x 3 = one yard x 1760 [sic] – one mile; and 16 ounces =
one pound x 2000 = one ton. Of course, each measurement is mathematically isolated
from each other. Why should life be simple if you can complicate it? Still,
over the years, people get used to the system and even intuitively assimilate
the weird math, even insisting on its virtues. However, there are some specialized
English measures that few Americans or Brits have the faintest idea of what
they really mean. They exist for distance, volume, speed and weight. Kudos for
anybody that actually can quantify them.

Furlongs and leagues are unusual units of lengths used for a specific circumstance. The length of some horse racing tracks is in furlongs, which makes sense since a furlong (furrow-long) was a length of a common plowing area in England, which obviously involved horses. Its length was 660 feet or 201 meters for those in the Continent. Many readers know that Captain Nemo could take his ship, the Nautili’s, 20,000 leagues under the sea but few realized that meant a little more than 69,000 miles or possibly 80,000 km if you use the French measure, a feat somewhat hard to believe if you consider it. A league is the distance a person can walk in an hour and varied accordingly. In the UK, a league was considered 3 miles while at sea, rather Jesus-like, it was 3.425 kilometers. I suppose walking on water creates less friction and resistance. Alas, it is rare to find anybody that walks from city to city or plows fields with horses. Too late, the damage is done.
[barrels] |
Oil and wheat prices are of prime concern to people throughout the
world. Their measurement is a bit mysterious. When the oil producers of
Pennsylvania decided to establish a standard packaging size in 1872, they
chose a barrel of wine, which contains 42 US gallons or around 159 cubic
meters. A barrel is a barrel is a barrel? Even more ancient is the bushel, a
unit of measurement for grains. The equivalents are 64 pints and 32.36 liters. I
suppose one can blame the French on this one as the term comes from old French.
I imagine only farmers there can
visualize that quantity. What was, is.

I would call this post “ode to the metric system” but Americans will
never abandon their time-honored tradition of complicated calculations and not
only out of respect for their math teachers. I am no Don Quixote. More
impractically, I can say after more than 30 years in Israel that I have
forgotten what heavy a pound is but still have no sense of how heavy a kilo is.
Regarding most measures, I can delicately ask a similar question to that Noah
asked God (at least according to Bill Cosby): what is a cubit?

A ship will have a speed of 23 knots, not knots/hour - 1 knot = 1 nautical mile/hour.
ReplyDeleteFunny but that is what I initially wrote. Should listen to instinct.
DeleteWay back in navigation training I learned to measure walking distance by counting paces (double step, one step with each leg) and I figure a mile is approximately 1000 paces.
ReplyDeleteThe Roman mile was a tad shorter than the present day mile and was a bit closer to a 1000 paces.
Given their love of decimals, the Romans would have loved Bo Derek!
