Shame on you, Bruce, that would take the outout of Hoover Dam a few 
centuries to calculate, not to mention there aren't enough digits on all 
this planets monitors to display it without using googles worth of 
digits in  +ee notation.

I do have to admire that though, beats the daylights out of furlongs per 
fortnight at C speed. ;-)

There's a Wikipedia article for people like you.

When I first heard that Google would do unit conversions, I naturally
asked it how many teaspoons are in a cubic parsec.  That could be handy
to know some day.

Annoyingly, though, metric cutting speeds are quoted in m/min which
introduces a pointless sexagesimal unit into all calculations.
Though given that we quote spindle speeds in rpm rather than rad/sec
perhaps this is allowable.

My favourite wierd unit is the megaparsec.barn. It's a about a
teaspoon, but very long and thin.

As an American engineer, I almost invariably convert my "real world"
units into the metric system, solve the problem, and then translate the
solution back into the units that are used in my country.  Cumulatively,
it's a significant competitive disadvantage for a nation, but it's
easier than trying to solve problems in nonsensical and arbitrary
imperial units, and it's apparently easier than trying to convince
Americans to accept the logical system of measurement that's used by the
rest of the planet.

Forget measuring cutting speed in mm per second.  What is it in furlongs
per fortnight?

In the UK we buy milk by the litre. Either 0.568litres, 1.13 litres or 3.408 
litres. 

The Student Union Bar At Imperial College is called “568” in recognition of the 
customary volume in which its wares are supped. 
(There is another bar called “H-bar”. Probably babes by Physicists.

Yes, people who complain about the metric system apparently don't realize
that they are using it without even knowing it.  The United States adopted
the metric standard for the inch in 1959.

All of our customary units are now defined in terms of the metric system.

Good points Peter. I recall an experiment we did, 40 or so years back, 
selling gasolene by the liter. Gas stations that installed pumps 
measuring in liters went bust because it wasn't an easy conversion & 
most thought the liter pumps were ripping them off, so they'd drive on 
till they saw a gallons sign. Old measures die hard was the takeaway. So 
we still buy milk etc by the gallon or meats by the pound over here. I 
hoped it would snowball at the time, but to the working public yelling 
at their government it was a PITA.

And that to this day still confuses the reloaders who load their own ammo 
for old meat in the pot. A gram of smokeless powder is a lot, compared 
to a grain, which is what our scales and measures are calibrated in. 
IIRC 437.5 gr to the ounce.  Then some use the troy ounce and some the 
imperial.  Sigh.  Its a conspiracy according to many, enough are voters 
to control it in the long run.

And by the way, (maybe already mentioned?), the inch used to vary in length
until it was defined as a function of the metre.
So the Americans are working in metric, but converted by 2.54  ...

P.S: People who are used to sixteenths of the width of a medieval thumb,

Andy,
the use of those length units depends on the circle who uses them. 
Woodworkers use cm, metalworkers mm, opticians micrometers, nuclear 
scientists nanometers. The aim is to leave off unused zeroes, either 
in front or after the decimal point. Hectoliters are the most 
important measure of beer hereabouts because it is convenient to 
simply count barrels instead pouring beer in bulky liquid measures, 
and Austrian houewives buy their sausage and meat in Deka's.


By the way, the Gramm is very well named after a dead scientist: Saxo 
Grammaticus, living in the middle ages around 1100, famous Danish 
historian, who wrote a history of Denmark in 16 volumes. He even 
attempted to write an English grammar - English and Danish were not so 
far apart in those days -, but failed because it would have become too 
heavy for the reason of the many exceptions to its rules (at the time, 
there were such). Therefore, the unit of weight was named after him.


My best regards!

I am a bit annoyed that the base mass unit is the kg, ie that it has an
embedded prefix. That is one unit that could very usefully be named 
after a

dead scientist.
