maybe we should switch to driving on opposite side of road while we are at it.

Our bus is plumbed with pex from the roll. Yes definitely a bit tangly.

Think about this. "Give them an inch and they'll take a mile or "Give them a 25.4mm and they'll take 1609.344 meters, nah doesn't sound right to me either lol!

If the US would stop acting like the British Empire in decline used to, and get with the program...

The rest of the world uses metric, even the British have given up...

Your turn?

Happy coaching!

As a Brit, I agree! At least the USA is in the hallowed company of those only other non-metric industrial superpowers of the world, Myanmar and Liberia. Go for it, roods and furkins!

We were close to the switching to metric in the 70s. Our entire school had switched over after about a year of practice. Then it became political in Washington and we all know how well that works out.

Ever since we've been dealing with vehicles and machinery with both metric and SAE hardware. What a mess. Pick a plan and stick with it.

Back to plumbing... Copper might be the gold standard of plumbing for many, and at on time was the only long lived option, but today there are a few reliable methods. Pex has been around long enough to pass the reliability test, and it can't be beat for ease of install.

Another advantage for pex is that it's lightweight. Many brag about how heavy their coaches are, but carrying extra weight is not a good thing. Pounds add up, whether it's plumbing or plywood.

I remember in the 80 GM models when they started to change over to metric fasteners. Had to buy10, 13, 15, 16, and 18mm wrenches and sockets. Then the current metric cap screw replacement had a 17mm head instead of GM's 15. Still seeing both types on various products.

We are getting there slowly but steady,the metric system has been used on fuel systems on engines for many years because you can get closer tolerance with the metric than SAE lol I still prefer the SAE ,and like the range of grades you can get on metric bolts though,wheel studs are prime example no need for 2 different nuts on wheels now

OK think about this. Metric sizes are less than ideal. When was the last time you used a 16mm or 11mm or 9 mm or 7mm anything? OK, maybe 11 but rarely. So why are they even there? Can't really say that for fractional sizes. And as far as the ballyhooed metric accuracy, I call BS. That's just numbers and you can work in tenths of a thou just as easy as metric and lots of people do and to the same standards of accuracy, which is the limit of what the technology enables.

It's just more European market manipulation. The US is the largest market in the world so how is it that the little guys get to determine the standards? Purely political economic warfare and our esteemed electorate has been too busy lining their pockets to see the big picture. Which is business as usual I guess, but you'll notice that these pockets of resistance aren't going away and that's for the very simple reason that they are right. So you want your steel and aluminum plate in metric sizes now do you? Yeah, I can see that happening real soon. Just about the time the US shuts down production entirely and probably not even then.

But the same argument of old verses new never changes, and progress is made at something less than the rate that it is shown to be commercially advantageous. That's important enough to say twice. Commercially advantageous, not politically feasible. Never fast enough for the young and never slow enough for the old. So what's new?

use 7mm all the time. GM uses those on small dash fasteners for years. 16MM Used on power steering bracket and inverted flare lines for power steering and other lines. 11 and 9 mm rarely used except to fit a smaller nut that is rusted bad and pound the socket on.

It may be BS tear into on the high pressure rail system it is going to be metric made in the USA Cat went to metric years ago on their injection pumps for better fuel injection spray pattern measurement,all fuel injection is done in metric now made in the USA lol your series 60 in the MCI is about all metric ,you will find 16,11,9 and 7 on those so keep those handy

Isn't google american?

The European Union is one of the most outward-oriented economies in the world. It is also the world's largest single market area.

They also outnumber you.

But that's just more fake news?

I never used the Sharkbite,in H/D yesterday I looked at some wow it could cost a lot to use those for a plumbing job,a 25 buck crimping tool and 6 bucks for rings would be cheap.I have a ? when the instructuctions say not "recommend for use behind covered walls why would you use those. They look to be the same principal as the push on air fitting that I change out all the time for leaking on buses.Suppliers gouge you for compression type DOT fitting to replace the push on too I pay 5 bucks ea for a friggn 1/4 in DOT compression fitting about the same as a 1/2 inch Sharkbite ,lol I can buy the push on 1/4 inch DOT fitting for $0.80 each WTH

To all who are saying the metric system is so great. Not all metric bolts are the same. I owned an import car repair shop for many years. We pretty much worked on anything from any country. If you were working on a German, French, or Italian car you would pretty much use odd numbered wrenches. IE 9,11,13 etc. If working on Japanese cars it was even numbers. Everyone used 10 and 17. Some German cars you couldn't just grab a 1/2 inch wrench for a 13mm bolt head, it was too small.
Thread pitches weren't the same either. I only found one bolt supplier that could furnish the correct bolts and head size for everything I worked on. I tried to keep things as they came originally. My bolt supply was huge.
When Ford started building cars with German engines, anything that was bolted to the engine after it got here had inch size bolt heads with metric threads. When England switched there were Triumphs with brake systems that were metric on one end and inch on the other with an odd junction in the middle to hook them together.
Don't say it's easier, even after all of those years of that, in order to visualize the size of something I have to convert it to inch.

I came across the different countries metric size in 70's what a pain it was.Sonja has a Triumph with the 1500 cc engine that thing has every type bolt made I think,I still like the grade 12 metric bolts though
