Can anyone name a product (or products) that is on the market today that is of recent development that is an international "imperial standard"?

Example: CDs are of recent development but are metric.

Vinyl records spring to mind.

Oh, and marathons.

Can't be bothered to do a list - you'll only fantasize.

Both of the above are metric....thus a bad example.

Neither set of dimensions is very "round" so I don't know if the case was designed metric or Imperial, but virtually all modern electronic components (used inside in the circuitry) are sized in metric, even if nominal Imperial dimensions are also listed.

I should have emphasized the words DESiGNED, ENGINEERED and MANUFACTURED. Not something that was converted after the fact in description only.

4.1 inches = 104 mm
2.4 inches = 61 mm
0.57 inches = 14.5 mm

Before some lunkhead starts to post that the inches converted to millimetres should have some digits to the right of the decimal because that's what a calculator who show, i want to point out that if you take the rounded metric sizes and back convert, then properly round you'll get the same inch values.

The fact that the inch numbers appear in decimals is proof they they were conversions of rounded metric numbers. If they were true inches, they would be expressed in fractions of 16-th increments. that's one thing most calculators can not do...convert a decimal metric number to a rounded fractional 16-th.

"""Neither set of dimensions is very "round" so I don't know if the case was designed metric or Imperial, but virtually all modern electronic components (used inside in the circuitry) are sized in metric, even if nominal Imperial dimensions are also listed."""

They are made in Asia and that means metric design.

The odd numbers may come from too much back and forth conversions. It starts out metric as:

104 mm
61 mm
14.5 mm

Then someone converts it to FFU, then someone else instead of going back to the original, converts the converted number back to metric and gets something other then the original. Do this a couple of times and you'll be interested to see how far the actual varies from the advertised.

A very good reason to ban FFU advertising alltogether unless it appears as an afterthought with the original metric always present.

As well as vinyl records, there's wheels (car, bike, motorbike etc).

On my mini I have 5J-13, meaning 5 inches wide and 13" diameter.

Of course the nutbag-brigade could always go out in the pouring rain and measure accross it with a metric only draughtsmans tape and declare that its a nice rounded xyz.abc millimetres in DCO units and pretend they're actually metric all along!

How do you account for the following?

The city has had 33.03 inches since July 1, 2004, said Jim Ashbuy, climatologist at the Western Regional Climate Center in Reno, Nev.
http://www.sanluisobispo.com/mld/sanluisobispo/news/local/11580339.htm

According to Weather Service and Los Angeles County records, 0.68 of an inch fell in Quartz Hill, 0.83 at the Antelope Valley California Poppy Reserve west of Lancaster and 0.36 near Devils Punchbowl County Park near Valyermo.
The National Weather Service said 0.06 of an inch fell at Lake Palmdale and 0.04 at Saddleback Butte State Park near Lake Los Angeles

""" I was referring to "products" not weather reports. These are internally measured in metric and converted for the media, that is why they are in decimal inches.

Consumer products in the past used fractional inches to describe a products dimensions. Decimal inches started to appear on some products as a exact conversion to a true metric size.

My request stated:

Can anyone name a product (or products) that is on the market today that is of recent development that is an international "imperial standard"?

The words "on the market today of RECENT DEVELOPMENT would imply DESIGNED, ENGINEERED and MANUFACTURED. The terms had to be added later to clarify since people like you didn'yt get it!

"""As well as vinyl records, there's wheels (car, bike, motorbike etc)."""

Neither of the two items you list qualify as "recent". I'm speaking of recent like in the past 10~20 years, not the past 100 years. Like CDs/DVDs.

Disc records, whether made of vinyl or another material are metric and have been for over 100 years. They may carry an imperial name but their diameters are true metric. Thanks to their being invented by the Germans. Even if they were made in imperial in the US, they are made metric elsewhere.

Thus they don't qualify.

Wheel rims are also an old technology product that carries an inch trade name. Now that JohnS of Michigan is here, he may be able to tell us if the rims are still made in inches or made in metric.

Is a 15 inch exactly 381 mm or can it be 380 mm? What would a mechanical drawing have as its manufacturing dimensions, inches or millimetres. If it is made to metric specifications now, then it would be classified as a component that started out in imperial, but has since switched to metric.

This would be in the same class as Floppy disks, IC chips and other electronic components, computers, etc.

"""On my mini I have 5J-13, meaning 5 inches wide and 13" diameter."""

But is it made that way? Would the drawing that shows the dimensions show it as 5 x 13 or 127 x 330 or possibly 125 x 330?

"""Of course the nutbag-brigade could always go out in the pouring rain and measure accross it with a metric only draughtsmans tape and declare that its a nice rounded xyz.abc millimetres in DCO units and pretend they're actually metric all along!"""


Or an intelligent person, such as myself, can go out in the bright warm sun light and READ the numbers on the tyre. Such as P195/65R15. This means that it is a nice rounded 195 mm, so the rim width would also have to be 195 mm to fit the tyre. Thus the rims are metric at least in this aspect.

The 65 is the aspect ratio (=0.65). Twice the aspect ratio times the tyre width plus the rim diameter should equal the tire diameter. So my tyre diameter is (2 x 0.65 x 195) + 380 and that equals 633.5 mm.

The P-metric are now the most common type of automobile tyre in the world. I guess we can say that tyres fit into the category above of a product that once was imperial but now are metric.

As for bicycle tyres, there is also a transformation to metric, thanks to the ISO. As I said earlier, the ISO does not accept any units other then metric. If they create a standard it WILL be metric. If a standard was once inch based, it WILL be changed.



See: http://www.cl.cam.ac.uk/~mgk25/iso-5775.html

Metric bicycle tire and rim designations

Many of the bicycle tires and rims used all over the world are based on older British inch-based standards. However, their dimensions are defined and labelled today in millimetres according to the international standard format defined in ISO 5775.

For example, a normal "wired edge" tire (for straight-side and crotchet-type rims) with a "nominal section width" of 32 mm, a "nominal rim diameter" of 597 mm, and a "recommended inflation pressure" of 400 kPa is marked according to ISO 5775-1 as:

32-597 inflate to 400 kPa


The first number (nominal section width) is essentially the width of the inflated tire (minus any tread) in millimetres. The inner width of the rim on which the tire is mounted should be about 65% of the tire's nominal section width for tires smaller than 30 mm and 55% for those larger. The second number (nominal rim diameter) is essentially the inner diameter of the tire in millimetres when it is mounted on the rim. The corresponding circumference can be measured with a suitably narrow tape inside the rim.

The minimum inflation pressure recommended for a "wired edge" tire is 300 kPa for narrow tires (25 mm section width or less), 200 kPa for other sizes in normal highway service, and 150 kPa for off-the-road service.

The section height of a tire is usually identical to its section width (for tires less than 28 mm, 2.5 mm have to be added to the width to get the height). The overall diameter of the tire is then the rim diameter plus twice the tire's section height. ISO 5775-1 also defines how to measure tires and how to calculate the maximum dimensions of a tire (as needed for clearances) from its designation.

This link takes you too the ISO site and here you can see the ISO standard numbers for bicycles and motorcycles:

http://www.iso.org/iso/en/CatalogueListPage.CatalogueList?COMMID=1302&scopelist=

Which makes me wonder that they might have a standard for automobile rims,and it too will be metric.

YEEEEEEEEEEEEEEEEEESSSSSSSSSSSSSSSSSSSSSSSSS!

Another admission by MAllet-boy!

Ahem (adopts a childish pose) - "Yessssss"

"Thanks to their being invented by the Germans. Even if they were made in imperial in the US, they are made metric elsewhere."

Glutton for punishment.

"Thus they don't qualify. "

Poor excuse!

"Is a 15 inch exactly 381 mm or can it be 380 mm? What would a mechanical drawing have as its manufacturing dimensions, inches or millimetres. If it is made to metric specifications now, then it would be classified as a component that started out in imperial, but has since switched to metric."

A 15 inch wheel is what it says on the wheel - 15 inches. Measure it in metric and it becomes metric. If you had a gram (they're smaller than ounces) of intelligence you would realise why you are our (that's pro-eitherside) resident clown.

Hey look! I've got a 2 litre bottle of coke! Yet when I pour it out into this here measuring bowl (etc).

CALM DOWN! YES! It's made that way. Here's a hanky - get over it!

ROTFL!
No comment!

Measure it. Find that its out by a fraction. Then come back crying and declare its imperial.

<< so the rim width would also have to be 195 mm to fit the tyre. Thus the rims are metric at least in this aspect. >>

"This aspect" = "one warped mind"

<<The 65 is the aspect ratio (=0.65). Twice the aspect ratio times the tyre width plus the rim diameter should equal the tire diameter. So my tyre diameter is (2 x 0.65 x 195) + 380 and that equals 633.5 mm.>>

See if you can guess what the "15" is in 195/65R15?
By the way - my father used to own a chain of tyre fitting (amongst other things) stores. He sent me on a jolly to the Pirelli factory. You'd need to take your trusty mallet along with you!

<< The P-metric are now the most common type of automobile tyre in the world. I guess we can say that tyres fit into the category above of a product that once was imperial but now are metric.>>

the speed marking? What are you on about?

BTW in the late 80's they made a metric tyre (for Rover cars). They were scrapped by the 90's. If you want to know more grow up and ask. If you're simply going to measure a record and scream "no" all the time then don't bother.

You're ignoring the reality of bike enthusiats magaizines and shops.

Tell you what - find a website that quotes it in metric. That's bound to convince us.

He's already been arrested twice, P.

They tell him to put some clothes on and he just ignores them. It's not fair on the kids - that's what I say. It can be very traumatizing.

"""By the way - my father used to own a chain of tyre fitting (amongst other things) stores. He sent me on a jolly to the Pirelli factory. You'd need to take your trusty mallet along with you!"""

The key word here is "used to". You seem to think that time stands still and what was done 20 years ago still is done that way today. Standards and people do modernise, maybe not all, but the majority do. Leave your time capsule and come into the 21-st century. But then you will find a very robust metric using world.


"""You're ignoring the reality of bike enthusiats magaizines and shops."""

I would say some very small minority still do...mostly those that aren't up to snuff on the latest standards, but eventually they conform as the use of the old confusion fades. As more and more usage of the ISO numbers becomes prevalent less and less of the old sizes are referenced. When someone has to explain why a 26 x 1-3/4 inch of brand A isn't equal to the same size of brand B it becomes obvious the inch based sizing is flawed. When the only way to clear up the confusion is by using the ISO sizes, they become increasingly the norm. Those "magazines" and "shops" that don't refer to or pretend not to understand the latest standards or technology are usually the first to display the "out of business" sign on the front door.

The web pages below are from a tire site that uses old FFU, old metric (French) and ISO to compare the various sizing systems. The article in the 2-nd webpage has a very postive reason why ISO is preferred. The old sizes are mumbled-jumbled and confusing, even to those who claim to be experts. The simplicity of ISO will guarantee it will completely replace the old sizes in a matter of time.

http://www.biketiresdirect.com/information.asp?inf=tiretype
http://www.biketiresdirect.com/information.asp?inf=tiresize

Here is a bike shop in Puerto Rico explaining tire sizes. The jist of the article is that cheap, low quality tires will have inch markings and who cares if what you buy as a replacement is what is right for your bike.

To the person interested in quality, they are going to be concerned about the "bead size" which is the tires diameter expressed in millimetres and is known as the ISO number. Thus a true bike enthusiast will be more aware and interested in the ISO metric numbers and the non-enthusiast will only care that he has a tire on his bike that isn't flat and a cheap inch one from Wal-mart will suffice.
