Doesn't look metric to me:

The one I hate is HVAC "tons" and BTU's. What's even worse is the yellow tag that talks BTUs, hours and kilowatts to express efficiency.
Damn it, it's kilowatts out/kilowatts in, period.

This is a fact and has been since the 80' at he latest.
Again, idiot... this goes more toward individual Americans and the "average" a car company thinks their demographic carries.
Now, idiot... go try to find ANY American engine that uses an SAE head bolt or any other fastener on the engine.
ALL of the engines, transmissions, and other drive train components are metric and have been for decades.
That is electrical efficiency. Thermal efficiency is another animal.
So, a declared value for any competition should reflect electrical consumption *for a given BTU unit output figure*.
Like 10k BTU appliances.
Or 30k BTU appliances.
That chart would allow for a comparison, and *that* observation would allow one to assign an "efficiency" number to the industry product line.
I am sure that a big tonnage unit would perform better than a smaller one on a thermal efficiency view.

Snort! Over in microsoft.public.excel.misc there seems to be a steady stream of enquiries about how to enter feet and inches ("NOT metric feet!") into a cell for calculations.
French diameter is just the circumference in mm. it is a lot easier to check by wrapping a tape measure around the tube that getting a caliper.

I bet you lose sleep over things like SEER (BTUh/W).
Wrong again, AlwaysWrong. kW is a thermal measure, too. A watt is
3.4 BTU.
That would be a 34kW appliance.
100kW appliance.
SEER is just such an efficiency number. SEER is defined as the number of BTUs transferred per watt. Despite the bastard units, it works.
Good grief. There is no such correspondence. You can find high, and low, SEER ACs in all sizes.
That reminds me of when I worked as a contractor under government supervision. They had a rule that all purchases were to be in metric unless you provided a written justification for why you couldn't find it in metric. I ordered a PC-104 board and hadn't filled out the metric exception form and was told to do it. When I replied that the board
*was* metric they almost fell over. I guess no one had bought anything that *actually* was metric! Well, it was sort of. They had dimensions in both units and never were exact round numbers, so it was a wash...-- Rick
The other day I was cleaning out my garage and found a bunch of non-metric wrenches and I was wondering if should get rid off them. So I asked my mechanic if there were still cars coming out that needed the non-metric tools. He said all cars he had seen lately were designed with metric nuts and bolts. Well, at least that's a progress. But then, there are still those non-metric dimensions as your links show because they are probably aimed more for the public than engineers and mechanics.
Libertarian Socialists.
"We're living free in the wilderness. Now, where's my damn government oil check?"
And they often fail to account for the amount of Federal money that went into the infrastructure that let them move up there in the first place.
My favorite story: an Alaskan out somewhere on the Yukon River Delta wanted to build a house and found the cheapest way to get the building materials there was parcel post. So he mailed all of his concrete blocks and stuff, making the postal service rent a barge at a cost of some tens of thousands of dollar.

Only if it was a very clean break. All that ice breaks where it wants to. ;-)
That "push" was the _second_ time / attempt.
I get all hot and bothered....

Actually, barrels made for long haul shipping were made with thicker staves.
You should like this, because it show that I am not all stuck on the US.
This page has some good facts. There are many others.
They do and they don't. Sure the bands for amateur radio are all based on metric (meters/centimeters - for example my radio does 6m, 1.25m, 2m and 70cm bands. )
I still have old stuff that SAE wrenches are good for, but everything on cars seems to be metric these days with few exceptions. Some dimensions in that Chevy are obviously hard metric (the bore and stroke size of the smaller engine is 96/92mm). The larger engine is mixed.. metric stroke and 4" bore.
It's a hassle to design solely in mm when tool and material sources are largely from the US or made for US customers. More digits to enter when machining* because Imperial tools are more available and cheaper, less availability and sometimes higher cost of things like reamers, etc. I don't mind 6-32 screws, for example, provided they make them for me with Phillips heads (or Robertson or Torx). Flat blade fasteners- ugh. The coarser thread compared to metric standard zips in faster with the electric screwdriver.
Do any Euro socket sets use mm drives? All my tools use 1/4, 3/8, and
1/2" drives. It would be a total PITA if there were 6mm/10mm/12mm drive sets (assuming they exist) in the same work area.Best regards, Spehro Pefhany

Here in Australia, where we've gone all metric already, I'm still struggling with the concept of a metric pinch of salt.
