Did the US ever go metric ? Europe (minus the UK of course) did, and rarely
looked back. AFAIK (please correct me), the US never went metric. Don't they
still use Fahrenheit and all that weird stuff ?
Oh, and btw - those non-metric units are not "English units", but "Imperial units",

That I agree with - although I suspect manufacturers increasing will go for
the IEC standards - I used to work for StorageTek where an argument just like
this went on about 2 years ago - the IEC side won. Generally the hardware
people were all for IEC, and the software side less so.

No, the US never went metric.  That's why $200M Mars probes crash on
entry due to some idiot using English units as opposed to the NASA standard
of Metrics.  The funny thing is that Thomas Jefferson, an American President,
suggested the Metric system to the French while he was ambassador there.

As concerns the use of Traditional Units being weird, I would say that the
motivation made a lot of since.   The units were based on commonly
available natural units of measure, eg.

one inch = 1 thumb = 1 pouce 
one foot  = size of a foot = 1 pied 

Also, as is very appropriate to this discussion, the English Units
made use of powers of two and three. Eg.  

1 inch, 1/2 inch, 1/4 inch, 1/8 inch

3 feet equals a yard.

So, the English units were more attuned to nature.  The only thing
natural about base ten is that the majority of us have 10 fingers and
10 toes.

Finally, Farhenheit units are smaller so that they make more convenient
divisions: Eg.

10-20 is downright frigid
20-30 degrees is Freezing!
30-40 is very cold
40-50 is cold
50-60 is blustery
60-70 is brisk
70-80 is confortable
80-90 is warm
90-100 is very hot
100+ is Texas in summertime, WAY too hot !!!  ;-)


Finally, for those in Switzerland:

1. Why is it CH when only 30% speak French

2.  The French think that "octante" for 80 and "nanante" for 90
is downright goofy.

And all of us count that way.  Oh yes, the English unit is *so*
attuned to nature... this is why we have different measures for dry
volume, wet volume... avoirdupois versus troy weight... oh yes, energy
is measures in BTUs and power in horsepower... what is the conversion
factor between them (it has the dimension of time?)

Bullsh*t.  They seem more natural to you because you're more used to
them.  Anyone who hasn't grown up on the system think that Fahrenheit
is the ultimate in lunacy.

I'm assuming that you're questioning Jefferson's role.   Here are a couple of
quotations which show that Jefferson's idea predated the official 
implemenation.    I can do more digging if need be.

1791 - "Jefferson Report." Thomas Jefferson described England's weight and 
measures standards to Congress "on the supposition that the present measures 
are to be retained," and also outlined a decimal system of weights and 
measures of Jefferson's conception.

And:

As the scientists were experimenting in their laboratories, practical 
tradesmen were making themselves permanent standards. In 1793, during 
Napoleon's time, the French government adopted a new system of standards 
called the metric system, based on what they called the metre.

Fahrenheit units were developed by a different process than Celsius, but
they are both "natural". The Celsius scale is 0 = freezing point of
water and 100 = boiling point of water. The Fahrenheit scale was
developed less precisely -- 0 is approximately the freezing point of
human blood, IIRC, and 100 is approximately body temperature (Fahrenheit
may have had a fever :)).

Oh, and things like having 0 degrees being the temperature of -frozen water- 
isn't really that natural... no, we'd be much better off using averagish 
sizes of human body parts as a reference.

Oh, that's right, only users of the Imperial system can use these new-fangled 
"fractions". If only someone would invent a 1/4 centimeter, the metric system 
would be a viable replacement!

How about this: Seeing there is no commonly used unit smaller than an inch, 
people had to resort to using fractions of an inch to describe sizes. It 
works in metric too, but people just don't, because there are a wider range 
of metric units.

Yes, and three is a magical number decreed by God himself. You do have a good 
point, though, the Imperial system fits in quite well with our 
base-two-but-sometimes-three number system.

Brilliant. The system with the smallest units wins. Let me introduce you to 
the yocto-centigrade, where the boiling point is 10^26 degrees. Combined with 
the revolutionary new "decimal point", you can obtain never before seen 
precision in describing temperatures!

Well, certainly makes more sense when you consider how hard
it is to make ice at intellectual centers like Alexandria and Cordoba.
I suppose that if you lived in Iceland, then you'd have a ready
reference. ;-)

Ha.  The point is that it's easy to halve and quarter something while it's
much harder to one tenth something.

I don't recall that God ever made any special mention of three, but he

My point is that HUMANS cannot accurately measure temperature, so it
makes more sense to use a fuzzier system.   Unless you are an android
with a 555 timer chip embedded in brain, you are a "fuzzy" thinker on
things which are continuous in nature.

But then again, I suppose that we should legislate exact frequencies
of light so that no one can make any mistake as concerns what is
yellow and what is lemon-chiffon.  And if your eyes are test and
are found to be out of spec, you'll be subjected to psychotherapy
sessions because you obviously have personnal issues which
are preventing you from seeing colour properly. ;-)

Look, just so that you all understand, I'm pro metrics.  I'm just
saying that they were not all totally crazy.   It's not like before
1790 all the people who had ever lived were morons.   Indeed,
after further reading, I found that Jefferson rejected the French
version of the Metric system because he though that their
measurements were not accurate enough (and less accurate
than many Greek and Egyptian mathematicians had made
millenia before.)

32 Fahrenheit is the freezing point of water.
32 + 180 is the boiling point of water.
To avoid negatives an extra 32 degrees were added.
And we measure it in degrees because the designer of Fahrenheit was
thinking about how angles were measured when he designed the system.

Now measuring Celsius is in degrees is the cute one.

As for other topics in this thread.
12 is a nicer base than 10 simply because it has more factors.

And the US officially is on the metric system.  However usage for
common things hasn't changed over.  And no one has had the guts to
have a flag day, and kick out.

As for all of the mebibyte versus megabyte stuff.  While change is
awkward it seems much more comfortable to me if we change the expanded
for first.  And then put in the abbreviations.  Otherwise everyone
will think megabyte and write MiB, which helps little.

Thinking a megabyte is 1000000 bytes and a mebibyte is 1048576 bytes
is almost sane.  Of course the only way to be really clear would be to
have another term for a decimal megabyte, and just drop the old term
with it's nasty baggage.  Since we don't have that the problem will
continue on.  But having two terms at least lets us be precise.

OK.  I guess that this seems like an "Al Gore Invented the Internet" thing
except that the system that he proposed was of his own invention (if not
the idea of basing it on ten.) 

The facts are that a number of people in the scientific community had talked 
about these things off and on for centuries.  Thomas Jefferson is the first 
recorded government official known to have made an official recommendation 
for its use (again of his own derivation.)  Alas, the US government was not 
feeling _that_ brave yet, so they decided on an slightly altered system of 
Imperial units.   

As well all know, the French were fealing quite pissed off at everything
that had ever existed prior to 1789.  In 1791, a very much living Louis XVI 
summoned a commision to study changing the system of weights and measures.  
It was during the Reign of Terror that they started making Guillotines based 
on their newly fangled metre.   Now, did Louis die of a new fangled 
Guillotine?  My French history fails me here.

Actually, you're not far from the truth here. The best system (makes for
least numbers of weights you need to make for weighing, etc, etc) is
base e (2.7182...), which is best approximated by base two sometimes
three ...

 I think you've just answered your previous question - there are more
than one because its generally more convenient.  If you're using
horsepower for power then you should probably be using
horsepower-hours rather than BTUs (which are an admittedly silly
unit for most things).

You have: horsepower hours
You want: btu
        * 2544.4336
        / 0.00039301478

 Centigrade/Celcius have little to recomend them either - Kelvin is
the way forward, or Rankine.

nautical miles are defined as 1852 meters, the exact length of one second 
of longitude at the equator :)

YM "minute" HTH.


FWIW, from the units database:

nauticalmile            1852 m   # Supposed to be one minute of latitude at
                                 # the equator.  That value is about 1855 m.
                                 # Early estimates of the earth's
circumference
                                 # were a bit off.  The value of 1852 m was
                                 # made the international standard in 1929.
                                 # The US did not accept this value until
                                 # 1954.  The UK switched in 1970.


Of course, the number 21600 is also such a nice round number.

true, it is off, but for all intents and purposes 1852 is close enough :)

The land "mile" is based on a very logical thing too (at least at the
time).   Mile is the anglicised "mille" which is French/Latin for
1000.  And mille refers to the distance traveled after _1000_ paces 
of a Roman army regiment.

And, of course, the etymology of the word "knots" refers to the fact
that before modern spedometers and GPS tools, ships would gauge
their speed by letting a rope freely drag out of the stern of the ship
and would measure the number of equally spaced "knots" in the rope
that had rolled off the ship during the period of one hour.
