The US doesn't exactly use the Imperial system. The US adopted the British 
units before Britain defined the Imperial system. It's mostly the same but 
there are differences. A ton is 2000 lbs, the gallon is .83 of an Imperial 
gallon which trickles down to quarts and pints.

How are vehicles wheel/tire diameters in your country measured?
All the imported cars I see here in the U.S. have wheels and
tire size measured in inches.

Of course. rims are inches, tyre tread widths are mm.

Since the person I was asking said that only metric is taught
in his country's schools, I was wondering if people there just
scratch their heads in confusion when buying tires.

To me the metric system makes no sense. I don't grok it at all.
But fortunately in the U.S. the exposure to it is minimal.

I fail to see anything superior about either system, frankly

And I have used both nearly all my life.

You don't get far as an engineer without being able to convert standards 
rapidly and fluently in your head. Or on a calculator

The arguments are mostly people talking bollocks about stuff they have 
no understanding of, so they substitute violently defended opinions

Again *shrug*. Plywood is sold as 2.4384 metres long, instead of 8 feet. 
Its the same bloody sized wood

It is a complete storm in a bigots teacup.

Any US garage will be using metric and imperial all the time.

Any pilot will be too.

The metric system was imposed, i.e. forced, whereas the Imperial units are
traditional and hence far more natural.

Forcing an entire society to change is never a good idea.  To force SI units
in the laboratory, among professional scientists, may be an easy switch, but
to expect the general, unwashed, population to immediately embrace a new system
of units is folly.

Keep SI in the lab and let the common folk do as they always have done.

Then there is the issue of manufacturing.  Converting a large industrial base,
such as in the US, willy-nilly to SI units is a very expensive undertaking.

For example, virtually all lumber products in the US are cut to Imperial
dimensions.  The ubiquitous "stud," which is universal in construction, is
still the "2 by 4" being 2 inches by 4 inches by 8 feet.  I highly doubt
that any lumber product is cut to SI dimensions.  The saw mills are too old
to easily change, and the wood worker is too conditioned to think differently.

Also, most raw materials such as pipes, tubing, and other parts are still
produced in Imperial units because most everything classified as buildings
or infrastructure was built according to Imperial specs. 

It will be a LONG, LONG TIME before US society becomes exclusively metric.

On the other hand, NOT joining the world standards has its own cost.

Back in the 1980s, at a PPOE, we licensed a design for an electronic 
device. Having been designed in Scotland, of course all mechanical 
dimensions were given in millimeters. An older manufacturing manager 
wanted it "Americanized" and directed a summer intern to convert all 
dimensions to "traditional" measures. The kid got out a calculator and 
converted all measurements to inches with 3 decimals. When they took it 
to the metal shop, the shop foreman asked if they really needed the 
dimensions exact to 0.001" ? No, of course not, that would be way too 
expensive. So the old guy replaced all the measurements to fractional 
inches instead.

The resulting product never worked right, but had bad fits between the 
PCBs and the card cage, betwwen the chassis frame and the side, top and 
bottom panels, and felt warped when customers tried to mount it in a rack.

Of course, it was all stupid. The machine shop where they built it had 
mostly Japanese machinery, which could do inces or millimeters at the 
flick of a switch.

Your example is a little odd, because a "2 by 4" is NOT 2 inches by 4 
inches and has not been for decades.

A standard 2x4 lumber has actual dimensions of 1.5 inches thick by 3.5 
inches wide (38 mm × 89 mm).

This principle applies to other dimensional lumber as well, such as 2x6, 
2x8, and 4x4, where the actual dimensions are slightly smaller than the 
nominal size to account for finishing processes.

The cutting dimensions at the saw mill are 2" X 4".  After cutting,
however, the lumber is dried in kilns which shrinks the dimensions.

But the size of the lumber throughout the distribution chain is
always based on the original saw mill cutting dimensions.

One never walks into a lumber yard and asks for a "1.5 X 3.5."
It is always "2 X 4."

The same applies to all other lumber products.  It is a peculiar
system but one gets used to it.

What I find somewhat amusing is that, like most other DIY
people, I was forced to purchase a set of metric sockets
(at great expense).

Each socket is forged on one end to be a specific metric
size (e.g. 10mm) but the reverse end, where the shaft of
the socket wrench attaches, is forged to an Imperial unit
(e.g. 1/4 inch or 1/2 inch). 

The tools are actually a hybrid.

If a society is forced to go metric it should go metric
all the way.

Obviously you haven't bought a 2 by 4 lately.

That's all one *can* buy.

Trying walking into a lumber yard and asking for
a 1.5 x 3.5.  The sales clerks will call 9-1-1.

Well.  I'm going to have to try that sometime.

In the UK they are 2x4 but they call it 100mm x 50mm Planed All Round 
(PAR) so its actually about 40mm x 80mm

It is exactly the same wood that used to be 2x4. But its had the SI 
gender chagne applied
