Re: [time-nuts] Obscure terms
Can someone please put me out of my misery and tell me what these
stand for?
You must not be very miserable. Google usually does a good job of answering
that type of question. There are a couple of sites that collect acronyms and
several sites that collect slang.
In this case, the top pair of results are good hits and down near the bottom
of the first page is the Wikipedia page that covers it:
http://en.wikipedia.org/wiki/Hair_(unit_of_measurement)
Sometimes it helps to add acronym or slang to the search string.

Did the google thing. Got Royal Children's Hospital. Found nothing in
the first two pages. Gave up. Emailed time-nuts. Of course it was on
the third page.
Never thought to type it into wikipedia...
Thanks to all who have helped!

Yep, as usual Google is fantastic for this task. Asking, 'RCH
definition', I found out this:
Royal Canadian Hussars
Recognized Clearing House
Reference Change House
RCH -- Chile (international vehicle ID)
Railway Convalescent Home
Redundancy Check
Remote Control Head
renal compensatory hypertrophy (my clear favorite -- I'll try to
remember this if ever asked)
reproductive and child health
residential care home
Residential Children's Home
right cerebral hemisphere
Royal Children's Hospital
Small unit of measurement
Huh, what? That last one sounds right, so I followed the link and
learned this:
What is RCH?
One of the definitions of RCH is "Small unit of measurement".
Very informative! So much more than the original page with just, "Small
unit of measurement." One of the definitions of redundancy is "Being
redundant."
I know... As you have shown, the dedicated googler can eventually
sometimes find the desired relevant information. Especially if the
answer is already known.
As with most www experiences, sometimes what you find by accident is
more interesting than what you wanted, but there is no guarantee that it
will be easy, at all, to find what you really wanted.
There has been an ad on US tv recently for a competing search engine.
Real people give random orthogonal answers to simple questions,
suggesting the google experience. Marketing genius. But I never used the
new one. Let's try the same search on Bing.
Nope. The same random stuff, but it gets more random even faster than
google.
Sorry for yet another digression, but it was fun trying the experiment
and venting about seeing what I expected to see.
Hi Rex,

try the "urban dictionary", it's a very good reference for slang terms,
not safe for work for some, though...

One of the more interesting units used in the air conditioning
industry in USA in the past was
a measure of wall insulation which was tons per square foot per inch
per degree Fahrenheit.
That is the number of tons of ice per 24 hour period that must melt
to sustain a temperature difference
of one degree F per square foot of wall one inch thick.
Not far off furlongs per cubic fortnight.

It is clear that inventing new measures which hopefully was logical in
their original context has never been discouraged.
Some of them has ceased to exist while others has been refined and is
now part of the SI units.
I am still supprised that optical people talk about wavelength rather
than frequency, it's like they haven't grasped the effects of different
wave propagation speeds (which changes the actual length of the wave,
but not the frequency).

Or, what about "boiler HP" which has almost no relation to the HP used in connection with motors and engines.
They still use that measure of insulation, slightly changed, as R value: BTU/hr = 1/R * delta T(deg F) * square feet
Tons, as a unit of refrigerating capacity (12000 BTU/hr) is still widely used (e.g. My house has a 5 ton air conditioner). Small AC units are rated in BTU/hr (e.g. The window type units are 5000 or 9000 BTU/hr)
While somewhat weird, they DO have a practical basis. Before mechanical refrigeration, one bought ice by the ton, at least if you were big enough to be interested in a mechanical refrigerator, so it's natural for the makers of such systems to give the performance in units familiar to the customer (Hey, Mr. Meat Locker owner, I'm Mr. Carrier, and you're buying 10 tons a day of ice. I've got this machine here that can replace that, for only $X. Such a deal)
Once you marched down the BTU path, the (U.S.) R-value numbers make total sense. I think that in Europe, the R value is calculated differently.
