Your Host :slight_smile:

Dr. Aspler, I enjoy your signature “your Host.” I would only add, “the
Host with the Most.”

Thank you,

Sorry to be so dense but “How do you use them?”.

Hanuman’s reply:
Very easy actually, Fill one field with the value you want to
convert, and hit the “calculate” button, You will see immidiatly all
the other fields containing the values after conversion. To start
again hit the “clear” botton.

The metalcalc utilities are great, especially useful for me when
ordering metal.

Another conversion utility that people might find useful is a small
program called convert.exe obtainable at http://www.joshmadison.com/.

The program is freeware and works very well when loaded on your local

Whilst we are on the subject or units etc -

I have recently been getting a lot of enquiries for the states for
hand made wedding rings etc. Does anybody know how your US American
numerical sizes translate to our UK alphabetical ones? Or faling that
what the mm internal circumferences for each American numerical size

Also sometimes it is just not practical for me to hand make rings for
US customers and would love to be able to recommend a few people over
there hand making to customers’ requirements but don’t know any of
your work at all although I imagine you are all brilliant! What is
the best thing to do? Should I point customers at Orchid or would that
be a bit of a nightmare? Thank you in advance for your help, Harriet,
Hitchin, UK

Hanuman, your solution to Martin’s problem is elegant and timely.
Thank you. Much more efficient than Ron’s proposed Global Inch Police
concept. Geo.

Hello Harriet,

I'm sure a great list could be assembled of Orchidians in the US

capable and willing to receive your customers - probably even at
least one in every state. My suggestion regards your question on
sizing. Why not buy a set of ring sizers and mandrel with US sizes.
Go to this website previously mentioned on Orchid, and check out the
metal ring size tester & mandrels - supposed to have US, Millimeter,
International, and CU sizes.

Dear George,

Hanuman’s gracious gesture of providing us with a table of
measurement conversions merely points out the chaos that we live with
when it comes to measurement. We are now living in a nanosecond world
and using volumetric measurements which may have had their origins in
the number of chicken feathers which you could stuff in a dried
goats’ bladder.

I shudder to think that when I launch my web site featuring designer
cabochons that I may have to describe a stone as being 15/32" by 1
and 11/64" inches! Should I then describe its’ weight in ounces
avoirdupois ! On second thought, the majority of the world,nay,
even Americans, have adopted the metric equivalents for purposes of
specifying dimensions and weight of stones.

Change, leading to standardization, WILL occur…it is inexorable
and has nothing to do with popular opinion. It is the product of
massive universal forces which prompt natural processes to evolve
into ever more logical relationships not unlike survival of the
fittest. That which functions best is more likely to survive !

You don’t have to “police” change…it has a mind of its’ own.
Nonetheless, we can recognize the superior efficiency of a given
system and encourage its adoption. Furthermore, we can easily see
that in a world of mass confusion, generated by archaic and endlessly
disparate systems, there is a huge opportunity to dispel the chaos
that it engenders.

Those of us who deal on a daily basis with the general
public…especially the older segment, come to realize that humans
have a very hard time dealing with change. When our local supermarket
shifts stock around in the store as a response to computer generated
models of what is selling and what isn’t the older clientele go
berserk because they lose track of where things are ! Personally, I
am exasperated by the increasing complexity of modern automobiles.
You can’t do your own repairs anymore because they are too frigging
complex ! Nonetheless, you have to adapt! I used to think that the
smartest way to buy a car was to track down an old “cherry” that had
been driven very few miles by the proverbial old lady from Pasadena.
The problem is that you are probably going to have a devil of a time
getting it to pass a smog test and, if it has a carburetor, finding a
mechanic who can tune one is getting increasingly difficult. Nowadays
I am inclined to think that a better way is to get a car that is a
couple of years old and has had an opportunity to get the bugs out.
You then drive it for about eighty per-cent of its projected life
expectancy and dump it ! Furthermore, if you plan to take a lengthy
trip, you are better off renting a nice new car which, if it breaks
down in the middle of Death Valley, becomes the problem of the
agency. ( Not to mention the fact that it is cheaper to rent than it
is to own ,assuming that you are renting a car with unlimited mileage

Any way you look at it, the human experience is one of learning,
experimenting, improving…and, coping with change! Ron at Mills
