Default What is happening with metrication?

Does anybody know if Machinery's Handbook is in process of being translated
for metrics?

I hope not, but just curious to know what is happening at the shop level
regarding the elitist's quest for world dominion through centimeters and
ergs.

We are taking the lead in metrics here...starting with metric time.

I thought you were joking... Interesting site, but still don't know if you
are pulling our hair or are serious about this?

The obvious question would be why? Why would anybody want to shift into a
metric time warp?

Beats me. I could be wrong, but I suspect there is too much WW-II
surplus tooling in use for it to change any time soon.

I will admit that for thermal units, metric is wonderful (slugs per
cubic inch per fort night squared is a little muchg), but for pretty
much everything else mechanical, pounds and inches are hard to beat IMHO.

You should not have asked that question. It will only trigger the
counter-question "So why should we switch to metric system?"

OTOH, "metric time" only shows that "they" didn't understand it at all.
It should be called "decimal time".
I remember listening to AFN (when I was about 14) when the US tried to
explain and promote the metric system. It didn't help.

that metric time link is funny, what a thing to get used to THAT would be.
thing that surprised me was working on a '05 Ford Ranger seemed some of it
was metric (which surprised me greatly) and some is standard. jeez! i was
fumbling with sockets and wrenches trying to figure out which was which.
seems easier if they'd make it ALL standard or ALL metric.

How many inches in an Archane? Seriously, I can't seem to find out,
it's pretty obsolete but I'm trying to duplicaste some Archane threads.

It is a joke, whether the guy who is advocating it knows it or not.
The SI system is based on the second, and a WHOLE lot of physical
constants derive from that. The speed of light, for instance! And, that
bears on a whole lot of other units. So, if you change the unit of time,
practically all other units need to be rewritten. Anything dealing
with acceleration, electrical units, heat flow would be affected.

The basic measure of time on the VMS operating system was based
on microfortnights, according to some of their documentation. If
you calculate it, that really isn't too far off a second.

My experience in being in a number of machine shops at national labs
(which would seem to be a place metrication would start from) is
that few have left the imperial inch behind. The ONLY shop I have
ever been in, in the US, that used the metric system to a large extent
is the NIST shops. They DO have some WW-II vintage machines left,
and other machines that are natively imperial, but with the CNC
option to program in mm, or a DRO on a manual machine, they do it
in metric just fine.

A number of other shops take all drawings in mm, and convert every dimension
by hand to inch measure, and machine from that. Ugh - lots of room for
error in that approach.

Cars have been largely metric for over 20 years, now! The only imperial
bolt-head I know of on my 1998 Dodge Ram van is the oil drain plug. Oh,
yeah, the lug
nuts are the other imperial fastener on there. Everything
major in the inside is either 8 or 10 mm or a Torx fastener.

One hogshead is two buts.
A hogshead is 1-1/3 firkin

Just how many is: "A ****load" (answer: more than 21)

Thank you one and all. I think one of our advantages (of the few that we
have left in this country) is our steadfast abhorrence of the metric system
since virtually everything we do in the shop from design to final product
has evolved via the inch/pound/hp system. For us to change to adhere to the
so called world standard would be to lose our advantage. I can do so much
more with decimal inches and fractions, hp and Watts, than I can do with
metrics and I was brought up in a metric world. Had to learn the crazy
Imperial system, but once working in it have seen unlimited horizons not
possible with metrics... or not easy due to the confusion of zero placements
which invariably lead to errors. As in the Mars landing.

Can you give us an example of one of your "unlimited horizons not possible with

Also, I'd love to hear how the Imperial system prevents "the confusion of zero

I find it odd having lived and been educated in the US upto high school
graduation in 1982 that all the science subjects such as chemistry and
physics were taught in metric SI units right from junior high onwards.
Having spoken to others later I found out that had I gone to university
and done engineering in the US I would have had to learn foot poundals
slugs at university. Having done my degree in the UK I have never had to
deal with these units and probably treat them as oddities much like many
US people do metric units. One guy I did my degree with had a culture
shock when he did work experience during his degree in the US with a
company doing work for NASA and that was his first exposure to foot
poundals slug which they were using.

Sure. Something over 60% of our GDP is intellectual property in this
country. Since Benjamin and other founding fathers determined that
innovation would be our salvation, creativity has taken a leading edge in
what we are. When I learned that one HP was equivalent to lifting 550 pounds
one foot in one second I could visualize that effort. I could see myself
pulling on a rope with a dozen pulleys and living those ten anvils off the
ground and realized just how much power there is in 750 Watts. Because of
this link between human bite sizes of energy, physics and measurements I
have had the pleasure of inventing and putting to work over 300 tools or
gadgets that have made work much easier for factory workers in my zone of
influence. It is because I can apply horespower and intelligence to
processes that my customers are now enjoying billion dollar a year pforits
which would not have been possible if I could not invent and apply
technology. I tried this with metrics because that is what I had learned in
school in Mexico. But I lost it, I could not think in terms of one cc equals
one gram and that a zillion grams make up an erg... I simple could not
visualize it. Metrication is great in the lab, but now when putting up a 4
by 8 piece of plywood with 2 by 4s and spaced at logical stud distances.

Sounds to me like the fault lies in your visualization capabilities and not in
the measurement system.

Another thought regarding metric verses inch. I grew up in the US
learning inch except for the science subjects. Having moved back to the
UK which is now predominantly metric I learned to use that. At the
moment I use both systems but some sizes seem to fit inch better and
others metric. I have the luxury to work in both for my own stuff but if
designing for outside manufacture I would do it in metric. I haven't
really sat down and worked out why some dimensions seem better to me in
inch than metric but they do, I just pick the system that feels right
for what I am doing at the time.

Yes... When I design something I use the proportional formula as do most
engineers. When a calculation is made I can visualize in foot pounds,
inches, yards... whatever and make a quick check of my calculations which
are made in PSI, Ft/lb and so on. So if I see my figures simply don't make
sense... a 50 ft blond with eyes are blue... I know I've screwed up and go
back to the start. Try visualizing a blond five ft two in metrics. I can't,
so I don't go there.

I want to be able to use both systems. You have a great point there! Some
things are better visualized and worked in the Imperial, and some are better
in the metric... like when I'm working with small amounts of plastic or
stuff in the chemistry world. I don't think governments should impose one
system over another. I think we, individually, should be able to use
whatever system works for us. And if I can't sell what I make in inch/pounds
then it's my problem. If I have to convert nuts and bolts to metric in order
to sell, well then, that's what I'll do. We are in a supply/demand economy,
Thank God!

I'm going to call BS on you here - sorry. I agree that the US has too
much inertia in imperial units (and associated hardware) to change to
metric just to do it, but mks units work just fine.


Had to learn the crazy

The Mars landing screw up was the result of laziness: it is all too
common to use numbers w/o units, and it hit home in a big way because
they botched the initial burn as a result of just such malpractice. I
will admit that the risk is slightly higher when exchanging data in
electronic form, but that's all the more reason they should have checked.

Units will all cancel out, but the numbers left behind are valid only if
the units indeed match.

Both systems have their place and I am lucky to be able to use either as I
want. Thank God there is not a Hitler or Stalin up there dictating how
innovation is to be handled.

By the way, my garage sized machine shop works in both metric and Imperial.

My original question was to find out how much government mandates have
influenced machining operations. At one time there was a mandate from the
DOD that all bids would be from drawings using metric system. Did this blow
away after Clinton?

I found that on a Volvo engine I rebuilt (US version). The stuff on top,
that you might get at on a weekend repair, was all English (maybe we

metric.

The imperial system came about in a long protracted need for a common
measurement system. The units were created out of necessity and
therefore fit better for commerce and general use. The metric system
was designed without realizing the subtleties of the english system that
was around for centuries. The metric system was designed by the french.
They probably were drinking too much wine at the time.

possible with metrics... or not easy due to the confusion of zero

placements
which invariably lead to errors. As in the Mars landing.

The imperial system came about in a long protracted need for a common
measurement system. The units were created out of necessity and
therefore fit better for commerce and general use. The metric system
was designed without realizing the subtleties of the english system that
was around for centuries. The metric system was designed by the french.
They probably were drinking too much wine at the time.

Thank you one and all. I think one of our
advantages (of the few that we
have left in this country) is our steadfast
abhorrence of the metric system
since virtually everything we do in the shop
from design to final product
has evolved via the inch/pound/hp system. For us
to change to adhere to the
so called world standard would be to lose our
advantage.


You have already lost any advantage that it might
have given you at least 35 years ago when the rest
of the world went metric. No engineer would be
silly enough to allow an Imperial spec machine
into his plant unless it was a LOT cheaper than
the metric equivalent, as its just to much
trouble. Just buying replacement bolts is a hassle
in the rest of the world so forget about growing
your export business. Besides, China is metric so
that's where 80% of machinery will come from in
the future.

Have you heard about the dinosaurs?

Are you going to answer the second question
about how Imperial measurement
prevents one from making mistakes?

Marv


Yes... When I design something I use the
proportional formula as do most
engineers. When a calculation is made I can
visualize in foot pounds,
inches, yards... whatever and make a quick check
of my calculations which
are made in PSI, Ft/lb and so on. So if I see my
figures simply don't make
sense... a 50 ft blond with eyes are blue... I
know I've screwed up and go
back to the start. Try visualizing a blond five
ft two in metrics. I can't,
so I don't go there.



To quote Marvin again "Sounds to me like the fault
lies in your visualization capabilities and not in
the measurement system."

cars have been a horrible failure, lots of american cars are still a
mish-mash

we did work for a caterpillar OEM, and cat is all metric.

er, sort of.

We supplied electrical enclosures with 10-32 screws, hehehe

All of our inch dimensions were drawn into funky metric combinations

I do a fair amount of creating knock-off components, for 70's european
dirtbikes, and wartime german electronics.

I measure in inches, try to determine a nominal metric dim, then draw in cad
using inches to 3 or 4 decimals, depending on the feature.

that metric time link is funny, what a thing to get used to THAT would be.
thing that surprised me was working on a '05 Ford Ranger seemed some of it
was metric (which surprised me greatly) and some is standard. jeez! i
was fumbling with sockets and wrenches trying to figure out which was
which. seems easier if they'd make it ALL standard or ALL metric.

Cars have been largely metric for over 20 years, now! The only imperial
bolt-head I know of on my 1998 Dodge Ram van is the oil drain plug. Oh,
yeah, the lug
nuts are the other imperial fastener on there. Everything
major in the inside is either 8 or 10 mm or a Torx fastener.

I believe the whole country was supposed to be converted by the time I got
to ninth grade...but that was thirty five years ago so it should be any day
now.

It was a very foolish thing to do but they tried, and now we have a
mess. Metric was supposed to be easier to use. well Spanish is an
easier language to learn, so why don't we get rid of english and all use
spanish. I think the movement is starting already.

It is a joke, whether the guy who is advocating it knows it or not. The SI
system is based on the second, and a WHOLE lot of physical constants
derive from that. The speed of light, for instance! And, that bears on a
whole lot of other units. So, if you change the unit of time, practically
all other units need to be rewritten. Anything dealing with acceleration,
electrical units, heat flow would be affected.

Jon

Before SI people start criticize us for not wanting to give up our units,
I think it would be fair to ask why they didn't go all the way in the
first place and make time metric. As you say, it's too late now to make
amends. Evidently, that was one that the French themselves had difficulty
coming to terms with.
