It's been several years since the USA said we would phase into useing the metric system. What happened? I recall lots of protest and push back but my understanding was that it was a done deal. Now that we are useing both systems it's a pain. Frankly,I like metric because it's easier to use and our traditional measures make little sense by compairson. What is your opinion,go all the way metric,go back to standard or keep both?

I think we should go all metric, but a lot of people are afraid of change! it is expensive to change, but it would improve our foreign sales of our products if they were metric. I think most of our industry is slowly changing, and the medical field is changing, some clinics weigh me in kg. some in lbs.
I think it's a combination of cost to convert, as well as the fact that the majority of the public simply do not want to change.
I know I'd personally like for things to go back to all standard, especially in regard to equipment. I say this because with the standard sizes, the majority of fasteners are either USS, or SAE, regardless of the manufacturer. Yes, different head types will be different sizes, but a hex head will be one size of the other. What I have found with metric is the same size bolt might have 3, or 4 different sized heads, and that's just with the standard hex heads. That makes working on a machine a royal PITA, as you often need to take say a 15mm, 16mm, 17, mm, or 18mm, all with you just to insure you have the size. The funny thing is you often wind up using at least two of them for the 'same' bolts.

Chiefio has done some posts on the derivation of imperial units. Such as
https://chiefio.wordpress.com/2009/06/06/chasing-the-greek-foot/
Seems to make more sense if you have to use fractions, which he goes into in some of the other posts. And I'm with him on meaningless metric unit names

You may think metric is the way to go but it makes working on machinery a real PAIN!!! There are three "common" thread pitch standards in metric and 5-6 "special" pitches besides them. It makes the cost of keeping hardware to repair things be quite high. I keep two of the most common thread pitch standards and just those two make me have an extra $2500 in hardware that still does maybe 60% of the total "metric" stuff I work on.
I look at it the other way. Way back in the 1980s when this nonsense started we where easily the largest economy in the WORLD. Why the heck did the morons in charge think we needed to change to make all the "little" economies happy?????
So now we have a half breed system that has you having metric and English fasteners on the same machine. Don't think the stuff from the "pure" metric countries is all metric either. Many pieces have both on them as well.
Is there a metric Pipe thread???? I have never seen it if there is.
I worked evenings at a machine tool company in the early 1990s.One of the high ups thought that the change was so great he ordered all the drawing to be metric dimensioned only. Guess what. well over 50% of the machines in the entire plant where manual controlled machines. THEY HAD ENGLISH only hand wheels and such. So when you got a new drawing you had to set down and calculate every single dimension back to English. There was only ONE long bed lathe in the whole plant that could chase metric ball screws. They had to run it 3 shifts 7 days a week to met the demand. It took management several years to finally buy a few more Metric lathes.

Canada went all metric in 79.
Blue prints are in MM only, carpenters build in feet and inches.
Till this day all lumber is still sold in standard sizes as is structural steel, bar stock and tubing
Finding metric bolts is a night mare, all bins in farm stores are filled with standard bolts and nuts,.. not a metric size in sight.
Metric sizes have to be ordered or one has to make a special trip to a bolt and bearing house and half the time they don't have them either.
This is madness :roll:
I grew up in a metric only country, today i am more comfortable using standard as everyone i know still uses that.
The only times i like using metric is with machining as i have a metric lathe and the decimal system for small tolerances is far superior to standard. This lathe can cut any tread known to man.
And for the same reason i use metric for weights smaller than an ounce.
There is nothing wrong with standard weights and measures
The whole country is laid out in miles and acres, to try convert that to metric does not work worth a damm.
Cattle are weighed by KG's and priced by the LB.
Convert convert convert
It drives me nuts.:roll:

I remember the teachers were talking about going metric when I was in high school in the early 1950's. They were teaching some metric in college back then. Then everyone kind of forgot about going metric.
In the 90's, ADOT sent out a memo that they would be going metric in 2 months - but it never happened. Metric comes up periodically, but resistance beats it back until the next time.

I don't know if you'd consider it pipe thread per-se, but how about BSPT, or BSPP?
Go a step further into hydraulics and you've got GAZ, DIN, JIS, and a few others I can't recall off the top of my head.
Like we've got said when it comes to metric's and equipment, it's a royal PITA to say the least.
Have you run into any of the hybrid fasteners yet? Personally I've seen standard bolts with metric markings, as well as metric fasteners with markings that appear to be standard. It can make for a real nightmare.
Even worse, I ran into one on a Deere awhile back that was a stud that held a belt tensioner on. It had a metric thread on one end, and a standard threat on the other.

being as I live in Canada and we adopted the metric system in 1977
this is were we stand 38 yrs later
metric fasteners are hard to find in general hardware stores and cost 3-4 times the cost of sae
wood products are 2x4 2x6 etc 4'x8'
building practices are 16" on centre and are quoted on sq footage
food is sold by milliliters or kilograms but have lbs. oz. listed pricing as well
most things sold in length are sold by inches feet or yard or by the meter
speed limits are kilometers and weights are by kgs and tonnes which are larger than tons
gas & oil products are in litres
I always convert mileage into imp gal to miles (imp gal=160oz to US gal of 132oz)
weather reports are in celcius to me when they say its 30c deg out I still feel like its cold instead of 86f
rain & snow is in millimeters sounds like a lot when they report 100 mm of snow = 4in
most of the people I know over 35 use the older english system for most things and most under use metic so depending who you are talking to what it means when you say you where driving at 100
there's hundreds of other examples of metic english confusion
I have a pretty good understanding of metic but I was out of school before it was adopted here and for me was only breifly taught 1 week if I remember correctly
so for me I always think in the old way and only convert to metic if I have to
my kids on the other hand mostly think in metric
only one of them understands inches feet yds & miles but he has basic automotive understanding and limited building skills
to me the metric system sucks unfortunately I HAVE to live with it some
have you ever watched Top Gear the British version they mostly qoute miles per gal zero to sixty mph times lbs for weights and that show is primarlly aimed at the Europeion veiwer that has been metric a lot longer than Canada. In some cases they where metic before WWII

Ain't that metric complexity wonderful?
We've got a Fiat Allis 10 dozer and I now own a few more taps and dies to cater for non-iso threads. At least our local bolt store can provide.
Whereas with imperial we only have to be aware of the half inch trap between UNC (13) and Whitworth (12) tpi

What gets even more confusing is when they mix both SAE and Metric on the same nut & bolt combination. I run into this all the time when I work on my 1988 GMC pickup which was made in Canada. Two thirds of the truck are Metric but the other one third - parts made in the US but assembled in Canada - are SAE. I've even found bolts with Metric heads, but the nut on that bolt had Metric threads and an SAE size; so you need to use both Metric & SAE wrenches just to remove one bolt & nut.

Basically, it was a lack of will. As with everything, when faced with making a difficult change that's best in the long run versus doing nothing, most folks will opt to do nothing. Making the switch to metric is just a macro version of going on a diet or saving for retirement: it takes will more than desire to make a change. The will of state and federal governments to push metrification simply isn't there, and in the current political climate it isn't going to happen.
The only place where metrification has succeeded is in those industries where the need to produce and sell products outside the US outweighs the desire to placate US customers. Which is why the auto industry is pretty much 100 percent metric. Interestingly, though, nearly all cars, regardless of the country of manufacture, use 7/16 bolts for the seat belt anchors; apparently that's the only fastener that meets federal safety standards.

A better question is, why were we ever "forced" to accept metric? It was all about allowing foreign manufacturers to dump their stuff here. Seems like since we were the market they were after, why didn't they switch to Standard Measurement? Metric makes no sense for things like lumber and general construction. Never understood the need to change from normal measurement to metric.

I remember this debate long ago in school.
Gotta convert to be like everybody else.
Just kids but our answer was the same as now back then.
'why would I/we want to be like everyone else...?'
If one person is doing something right and 99 are doing it wrong...
the one has to change?? to be the same?....naw....
as always..follow the money...if somebody will get richer by
converting...they'll push it.
saw a comment about the auto industry.
Those hard-eyed bean counters don't care about placating us, or making foreign buyers happy either. Price per fastener times a billion fasteners....metric or standard...the cheaper will be designed in.
And foreign manufacturers of fasteners will keep pumping out the standard ones as long as we want them.

The metric system has been around a very long time. Congress has pass laws they want, require it to be taught in public schools, but many engineering colleges still liked the old school way English way using feet, pounds and a mass unit(can anyone tell me what the English mass unit is?). Metric system, meters, newtons and kilograms or cm, dynes, grams.
Most people don't know the beauty behind the invention of the metric system, how the length, mass and force units are all related. There is no rime or reason behind the English system.
The US does it own thing while other countries are metric. I remember when they tried selling gas in Liters.

I know I had a hard time telling my wife why I needed two sets of tools.
I prefer the english vs metric - it's just what I'm use to. Not intimidated or fearful of metric, but I don't think it should be mandated on the folks. The market should dictate metric - and I think that is happening. When we are working on the Honda car or Nissan truck, I tell the boys - 100% metric. When we are working on the old New Holland 68, english only tools. When it's a mix, it gets a little more dicy.
Funny story - don't know if anyone remembers Paul Harvey and his noon time commentaries. I LOVED those things! Back in the 70's when the big metric push was on in the US, Paul Harvey said in one of his commentaries that the US was the largest economy and we were the greatest country in the world and we didn't have to adopt the metric system if we didn't want to. My high school math teacher was talking up how great the metric system was and I raised my hand and told her what Paul Harvey had said. She promptly threw me out of the class room - LOL!!!!!

Not quite correct....
1/4 inch is 6.5 mm
1/2 is NOT 13 mm. 1/2 inch is almost exactly 12/5mm.
3/8 may be considered to be the odd one, but nothing else will fit 10, 15, or 18mm.
14mm wrench can reluctantly be used on 9/16, but is tight. 1/2 will fit about the same onto 13mm. Mostly due to allowing some clearance in the fit. Some wrenches will fit better than others.
BUT, metric and SAE sizes are not really compatible with each other. Just some can be made to work while others will not.

Let those forien countrys buy their own stuff, forget them. If they want our products they will go with SAE. Just how stupid is the metric system when on temp every degree will have to be figured out to 2.12 degrees so a temp of say 50 celcuis could be a range of 4 degrees farenheight and that much off can do a lot of damage. And never heard the word metric till years after out of school. I just know it is stupid.

Agree as Metric was the dimension of the industry I was in. Yes it makes perfect sense and all that. We just grew up under a different roof and got used to an antiquated system dumped on us by our ancestors. I too wonder what happened to it.
Confusing thing is that a lot of things that you buy today (most) are not all Metric. Some are SAE, some a mix, and some Metric. So when I tackle a job I bring half a dozen wrenches of both sexes. Used to be, when I was growing up and getting into fixing things, I prided myself in being able to look at a fastener and know the size.....JUST LIKE I COULD LOOK AT A CAR OR TRUCK FROM A DISTANCE AND TELL WHO MADE IT AND WHAT YEAR!!!!!!!!!!!!!!!!!

I remember back when I worked for the Kansas DOT (1990's)......We got word that the Feds were GOING TO mandate the switch to metric, so - Kansas being Kansas - jumped in with both feet and started the switch early. Everything - drawings, maps, plan sheets, etc, etc, were drawn up in metric. What we learned was - as soon as a contractor would get a set of plans, they would IMMEDIATLEY convert them back to English. Guys working with cubic yards and inches for 50 years, aren't gonna convert to mm over night. The whole big program was a HUGE waste of time, effort, and money, so they scrapped it. When I left KDOT in 1996, everything was back to English, except for a few highway signs....

The Metric system is simpler in the broader concept because weights and measures are all decimal fractions of each other; even in volume/weight functions----that is one ml of water has a volume of 1 cubic cm weighs 1 gram and takes one calorie of energy to raise 1 degree C.---Can't be any simpler to make conversions than that vs. 12 inches to a foot, 62.5 lbs to a cubic foot of water, 4 pecks to a bushel, 44 barrels to a hogshead, 16 links to a chain, 132 or 160 fl.oz to a gallon (Imperial) and I could go on.....Having said that, the "Gimli Glider" incident involved a brand new Boeing 757 nnalert jet whose fuel dipsticks were calibrated in Kilograms. Ground crew fuelled the jet, interpreting the calibrations in pounds. Thus, the jet left half fueled--since one kg is 2.2 lbs and made it just over halfway to its destination. Fortunately, the grew was able to dead stick the plane to an abandoned miltary field in Gimli, Manitba with no injury and only slight damage to the plane. Everyone got a refresher in conversions after that!!

Indiana Ken Very good coming up with the slug. How much does it weigh and the 64 $
question where did it originate form? What had a mass of 1 slug? It took me over 40

No. I didn't follow the mars lander that was lost (ran out of fuel) because this
conversion was not made? Back in my college days I was going to co-op with NASA. At the
last minute, budget cut backs, I ended up spending 2 semesters at UNSAD Crane in the

I see in Rand Paul"s gov waste report that we are giving a professor $188,000 to write a study on why the metric system failed in the US .
Pretty much all the present 'third world countries' of today had their 'place in the sun' at one time or another in the past but saw decline (due more to greed more than anything.) When it got bad enough there were mass emigrations from Europe to North America and the 'land of the free and the
home of the brave'. Now, there are some who think that we are not exceptional as a country and wish for the U.S. to be 'more like the rest of the world', especially Europe! :shock: In my view metrification is merely another nail in the coffin of American 'exceptionalism', BUT, that's just me. :evil:

There was a push to have the US all converted to metric by 1975. In the early 70s the speed limit signs had both mph and kph on them. Some even had the kph larger and on top. 10 years later very few of those signs remained as they were replaced through normal maintenance. Much of industry started to make the change in the early 70s. That is when you had cars and trucks with both metric and English fasteners.
Other than anti-friction bearings that have been metric forever, probably the first thing to appear in metric on US built IH tractors was the alternator mounting bolts. Delco Remy made that change in the mid 70s. The IH 5X88 tractors were designed and built as metric units. Parts that were used in older models were not changed so the engines and hitch cover are not metric but most of the rest of the tractor is.

Not a good comparison. Just as metric units are the measurement standard for international industry, English is the language of international business. Chinese and German students who want to be successful in international business learn English because it's a necessary skill. Businesses that want to remain competitive in the international marketplace go metric because you can't compete globally making products that can only be sold in one country.
