Metro vs SAE

[Frankenkubota]

Now that痴 a conversation! Now, try to have a CIVIL OBJECTIVE conversation about it.

My dad had a sign on his desk that said,

don稚 confuse me with the facts, my mind is already made up.

I知 not going to list the many reasons we should be on the metric system except to say, if you don稚 see the benefits you don稚 understand. If you do see the benefits and still don稚 agree, that痴 common, you are among friends.

2 things.....

1 we inherited our measurement system from the English. They don稚 even use it!

2. The metric system is used in 3 or 4 of the most important areas of your life.

A. Military is 100% metric. Rah rah all you patriots.

B. All those pills we take, pharmaceuticals, metric.

C. Go buy a quart of soda pop, oh yea, that痴 called a 2 liter.

D. Booze. When I was a drinker you bought a quart of whiskey. Now, metric.

I could go on and on but, I致e been kicking that dead horse for 40 years.

Too bad metric fasteners are not common between countries. They are all different wrench sizes and thread pitches.

USS and SAE were more common and easily identifiable.

Nowadays you have to grab 3 or 4 different wrenches if you don't want to make multiple trips to the tool box.

 

[Diggin It]

I personally don't care which, but I hate when they use both on the same object or machine. Same for switching between slotted, Phillps, Allen, Hex and Torx.

Metric is so far superior it’s not even fun. I get pissed almost daily trying to use the SAE system. If it wasn’t already stupid enough go ahead and throw your 10 inch foot engineer scale in the mix.

There are a std pitch on metric witch all countries are using, fine pitch are not so standardized as UNF. You have DIN, ISO and of course JIS.

DIN is oldest and is quite simple 7,8,10,13,17,19,22,24,27,30 and 32 are the wrench size that are in use. ISO has taken down the size a mm, 19 to 18, 17 to 16 or 15 but not all sizes, mostly the dimension that are most common in production.

It's not 3/8 it's 9,5 mm and 1/2 is 12,7

So what's the problem.... I have a American Car Company, truck, assembled in Canada using Chinese parts.....

I use what ever wrench fits bolt or nut or Allen socket head screw or TORX.....

Just be glad you don't own a British car that uses Withworth....

So why is your P metric tire mounted on a 16 inch rim?
Why is your 16mm socket made to fit a 1/2 inch ratchet?
We are supposed to be economizing, and yet, view the truck hp wars.
The US, with the Metric Conversion Act of 1975, was supposed to follow Canada.
And where are we 45 years later? America is kind of clueless with setting policies.

What system are you on in West Uncton ?

 

[Smokeydog]

Kubota tractors use several British hydraulic fittings mixed with JIC and SAE. British thread grease zerks too.

 

[stuckmotor]

All kidding aside, I agree we should be on the metric system and if metric fasteners aren't common between countries they should be.

BSP is used everywhere in Europe, the common pipe thread used on water pipes etc is British but it's size is give in metric 1" is called R25 here I live.

They are the same all over when it comes to thread size and pitch, they are so common that nobody except the US uses pitch on STD metric bolts, all else uses just diameter as the pitch is STD if it's not listed.

As far back as 40 years ago we had Made in USA carrot packaging machines that had SAE on the main machines and and a mix of metric and SAE on the bag sealing mechanisms.

Small Allen head setscrews are almost impossible to distinguish between the two systems.

 

[dodge man]

I would say it seems like most of the stuff I work on these days is metric fasteners. This includes vehicles, tractors and small engines. I am a land surveyor and our state DOT went all in on the metric system. That lasted just a few years and they switched back to English. I did a couple of jobs in metric and it was not to bad except leveling. I really struggled with the metric level rod. We had one long term job in design, started in English, changed to metric, changed back to English. That is spending the tax payers money wisely.

R25 would seem to equate to 25.4 mm to the inch.

SAE and Metric

I agree that the metric system has benefits, however not all metric measurements make sense. Specifically, wood volume. The metric system uses a cubic meter as the board volume unit. Not a very friendly or useful measurement for the cabinetmaker.

Cubic meter? 1000L squarebox doesn't make any sense if you are talking about boards, m or m2 is the usual way. m3 is used for firewood or truckloads of timber.

 

[Diggin It]

Nobody caught the 'metro' thing yet, eh?

"metro" is "meter" in Portuguese. 1 meter = 39.3". So, technically he is not wrong.
