After Coughdrop's brutal implementation of Metric - even telling us how to spell, "grams not grammes", un-Australian that's what it is, you just know 'Progressives' will try spelling-reform as well. Next Coughdrop toyed with nationalisation of Insurance...now he's gone too far, you don't mess with 'Big-Insurance', TPTB will take you out (using the good offices of the GG)

In US, Dementia-Joe is taking on 'Big-Pharma' - look out, don't mess with them!

I have a shifting spanner that does both Metric and AF Smile 😀

RR Merlin engines were Whitworth but the Detroit versions used US threads. I had a Villiers motorbike that was WW, so had to buy special sockets from Woolworth (Whitworth from Woolworth)

The iconic Vincent motorbikes are also WW, a really good standard that got shafted by metric - well almost, still used in plumbing!

QUOTE: Some Americans like to pretend that they don't understand metric, however anything they own that was made outside the USA is metric


Actually exporters convert to US standard for US market (makes it easier on the brain)

Actually the US chip industry moved to metric a while back.
And fine pitch SMD connectors are almost all metric.

It's so much easier on the brain!

I should know, I often have to design PCB footprints for new parts

Regardless of how it's marketed, a mechanic or technician still needs metric tools to work on imported equipment.

And since around 1980, American engines have been made to metric standards and, as far as I know, no one yet has been declared insane trying to cope with that.

And the world didn't stop in 2001 when US stock markets went decimal for stock prices.

IMO America will eventually convert to metric ... albeit likely inch by inch. Wink

The V6 engine in my Commodore - made here but to what was originally a US design is a bit of a frankenstein when it comes to the nuts and bolts that hold it together. It has a mix of metric and imperial all over for some odd reason. It doesn't matter that much, as in many cases metric and AF sockets and ring spanners can be used on each others fasteners, whilst in a few cases, the size isn't exact and can result in damage to the fastener - usually rounding off of the head. On the imperial fasteners, there is also a mix of course and fine threads, just to add to the variety.

If this GM V6 is the one I'm thinking of, it has a valve on the fuel-rail for monitoring fuel pressure, am familiar as I changed the fuel pump in my Buick and pressure was around 30 PSI? The humble Schrader valve hasn't changed in 100 yrs - thus has US thread!

Yep, sounds right. My old VS had a V6 Buick.

Basically the same design - Buick designed the original version of the 3.8 litre engine in the 1960s but there are now several localised versions all over the world. Holden, Vauxhall and Opel went on to build this engine for their cars. This engine went for longer than Holden's famous "red motor", which only had a run of 17 years.
