Pierre, Pat & all:
Re-defining *metre* as: '1/10^5th of (pi/180) - i.e. ONE degree' as
discussed in my posts since mid 2002, when tied with DECIMALISED *Hour of
time of the day* has its advantages.
Imagine: 24hx60mx60s = 24hx100mdx100sd maintain the existing 15-degree
HOUR-Angle that make NO deviation BUT improves upon 'prevailing confusion'
to Le Systeme Internationale d'Unites (SI-units). See: my contributions at:

I have seen the idea of using 'only powers of 1000' in many places where it
is often referred to as the 'Rule of 1000'.
I suspect that this is not so much a rule of 1000 as it is a convenient way
to rid a particular area of measurement of fractions -- both vulgar and
decimal.
As an example, suppose that you are a soft drink bottler and you decide to
buy your ingredients in cubic metres (kilolitres) and litres and to sell
them in millilitres. You then write your company policy like this:
> The Pleasure Pops drink company will use millilitres, litres and
kilolitres
> for measuring volume or capacity centilitres, decilitres, decalitres,
and
> hectolitres will not be used.
>From then on, there would be no further need for the use of any
fractions.
Granted there would be turmoil and discussion when someone suggested a
container that was 1250 millilitres. Some would say that this goes against
the 'Rule of 1000' in that it has a number larger than 1000. Some would
then
want to call this 125 centilitres to remove the trailing 0 and to bring it
back inside the 'Rule of 100' limit. Others would want to call it 'one and
a
quarter' litres so that they could show off their knowledge of fractions.
However, if the policy (written above) was formulated and encouraged, there
would always be a definite policy advice that would invariably produce the
simplest possible practice.
By the way, for those who have not seen it, the article 'centimetres or
millimetres which will you choose' is available as a pdf file at
http://www.metricationmatters.com/articles/ and it is near the top.
Although
it is a long article, you can get the sense of it by only reading the
introduction (2 pages) and the conclusion (3 pages).
