Which reminds me: It's not known as "German Engineering" for nothing.
These top-notch masterminds use the metric system. When was the
last time anyone extolled the virtues of American Engineering? Or,
British Engineering? As a global customer what sort of engineering
might you pick of those three?

As a Canadian he has experience working with both systems.
He prefers the metric. It's easier to learn and easier to use.
I also prefer metric for those same reasons.

It seems natural to want to divide units into halves, thirds and
fourths. It's not often that a person needs to levitate a
dust particle to the moon. But note that it takes more
mental effort to divide a meter into thirds than it does
a foot.

Which is also a reason for choosing Cosmetology school
over Engineering.

That is obviously evidence of a homogeneous ethnic environment where you

You overestimate the propensity of people to change when there are many
clear good reasons to do so. Inertia counts for a lot in politics and
general management. Indeed, it probably counts even more so in politics:
it's extraordinarily hard to undo something. Just ask the U.S. Congress,
European Commission, or the Japanese Diet [1].

Oh, so it's bad just because it's French? If you want to boycott French
ideas, please reverse all of your chemistry knowledge back to
discussions about "phlogiston" (possibly even earlier). Which probably
means you should give up all synthetic fibers or drugs. And you'll
probably need to start learning to sew by hand, for I believe the French
were instrumental in the development of sewing machines. And the French
also made significant forays into mechanical looms (including, most
notably, the Jacquard loom, the first use of programming a century
before the Babbage engines and two centuries before the first electronic
computers).

And having a French acronym does not necessarily mean it's a French
invention, to boot. French was, and still remains, an important business
language. Until the middle of the 20th century, it was more likely to be
the international language one learned instead of, say, English.

One of the Mars rovers crashed into Mars. Why? Because one group of
people were using SI units and the others Imperial units. I'm sure that
the potential damage due to mixing up unit systems is much worse than
mixing up languages. This would mostly be due to the fact that you often
calculate using units and not with languages. Unfortunately, trying to
statically cart around units is a lot harder in practice than you would
think.

Except the fact that approximately 5.3% of the world population (U.S.,
Liberia, and Burma) uses the Imperial units and 94.8% use SI. Even if
you want to measure by GDP impact, you've still got a hefty 20-80% split.

The cost is in conversion, period. Mostly because most people of my
generation would be used to thinking in Imperial units as opposed to SI;
for Europeans, they would be used to thinking in SI. I have a pretty
good intuition of what 50�F looks like, but not of 20�C. The inverse
would be true for non-Americans.

Here are all of the prefixes that I see commonly used for measurements:
milli
centi
<none>
kilo

Most people will know of "mega", "giga", and "tera" from computers, no
matter where they live (even if there is confusion between 1024-based
and 1000-based values for these units).

How often do you measure stuff in terms of 10^21? Indeed, the media
seems to think that most people already can't handle numbers larger than
a trillion (million billion and billion billion starts becoming popular).

You've magically missed the argument that most people use when
advocating metric: units are a lot more intuitive. How many feet are in
a rod? How many square feet per acre? Acres per square mile--are you
talking about statute or nautical miles? Please convert knots to miles
per hour. And then there are fluid ounces (distinct from avoirdupois
ounces and troy ounces!), gills, cups, pints, quarts, gallons... and
barrels and hogsheads.

So, if the United States imports 13.1 million barrels of oil per day,
and the average car gets 27 mpg, how many miles would the average car be
able to drive on the imported oil, assuming perfect conversion of oil to
gasoline?

[ Snip hoopla about base units ]

Base units really don't make that much of a difference. Consider it a
historical aberration.

I seem to use radians a lot more when doing calculations. And I'm sure
many surveyors may prefer gradients to degrees.

You are so insensitive, you know that? What about the Japanese and their
koku of rice? Or their ri? The Chinese li? The ancient cubit? You're
being so Amerocentric. And what about the Anglo-Saxons' units, before
the Romans imposed their unit system onto them?

[1] I know, I know, I shouldn't be so biased towards the
economically-advantaged nations, but unfortunately my media sources
provide me with too little information on third world countries.
