(quoted from post at 06:43:33 11/26/20) Well at least somebody sees the advantage in the metric system ..... ha! Good one .....

Don't forget, a ten gallon hat would be bigger in Canada. 45.4609 litres. Because of our imperial gallons. If anybody in Canada still remembers the imperial gallon.
 
(quoted from post at 08:56:23 11/26/20) We don't have the metric system in the US because we don't like foreign rulers! Only 3 types of people use metric in the US scientists, immigrants and drug dealers.

Amen to that.
 
I googled it!

The metric system is the most widely used measurement system in the world; it is also the primary measurement system used in the medical field. ... They must also be able to perform accurate calculations with measurements and express the results with the correct unit notations.
 
Just about everything on an automobile is metric and has been since the 1980s.

Prior to that, most (if not all) spark plug threads were metric.
 
You need to create a form letter to inform JD, Caterpillar, Ford, GMC, Boeing, and a thousand other productive companies based in the USA. The letter needs to explain why we cant sell the rest of the world our production because it uses an obsolete system of measurement. Jim
 
Good pun with the foreign rulers BW, and you didn't list your military ....... and speaking of "rulers", where the heck is he?
 
What was bad were the years the American cars were mixed.

Better have a good memory going back together!

I remember there was a NASA satellite fail because of confusion between metric and American components and the overlap of specs done in both measurements.
 
I seem to remember that the US was going to change to metric late in the 1700's but for some reason congress didn't. Maybe still some resentment toward England???? US is out of step with the rest of the world. I have worked on cars, trucks, tractors and foreign motorcycles and I prefer metric. I have found less problem with stuck (frozen) bolts or nuts that are metric.

I don't recall ever using a metric socket on a spark plug in the 50+ years I've been removing spark plugs. Guess I haven't done enough wrenching on my newest vehicle (97) to say for sure what it has for metric, or not, fasteners.
 
Its a joke...sure is a lot of grumpy people out today! The fact is metric is alot easier to use if you grew up with it. The mm and cm is easy for me but temp is where I have trouble converting off the top of my head. If we want to complain let start on British threads! I have a box full of adapters at work so when we get a British made engine in I can hook up the instrumentation to it.
 
1866 it was made the legal system, but never mandated.
Then ---The Metric Conversion Act is an Act of Congress that U.S. President Gerald Ford signed into law on December 23, 1975. It declared the metric system "the preferred system of weights and measures for United States trade and commerce", but permitted the use of United States customary units in all activities.
We are metric, but fail to let go of a much more difficult system. Base 32, base 12, base 3, base 16.5 (rod is defined as ​16 1⁄2 US survey feet, equal to exactly ​1⁄320 of a surveyor's mile, or a quarter of a surveyor's chain, and is approximately 5.0292 meters. The rod is useful as a unit of length because whole number multiples of it can form one acre of square measure. furlong, Base 5280. And don't forget: fractional drills, wire gauge drills, number drills, decimal drills, and letter drills. WOOF Jim
 
"The fact is metric is alot easier to use if you grew up with it." Well Duh! I suppose the same thing could be said about the Chinese language.
 
Ouch! My head hurts. Tell me if I’m wrong. An elevation of 108.2 can be converted to 8’-2.4” or 8’-2 13/16” which is 249.936cm or 2.49936M?
 
gas millage is simple
KM divided by litres X 282 Then just move the decimal 2 places when you look at it on the calculator
 
The hex on the most common plugs are either 5/8 (16mm) or 13/16 (21mm). Threads are most commonly 14mm with the
older larger thread being 18mm.
 
Chinese would be as easy as a bunch of stupid numbers that mean nothing about anything . The US system is easy it’s how many pieces of a whole pie 🥧
 
Still holding out hope eh? They'll likely have to drag him kicking and screaming out the door. Oh well, it's like a football game where half the people watching can't seem to accept the loss. Eventually you'll get over it as difficult as that might sound but it'll happen.
 
Henry Ford used 1/2 NPT thread sparkplugs in his model A's maybe others. He did not want to have European parts in his cars. At least that is how I remember something I read a few years back.

The wrenched part is SAE but the threads are metric. eg: 14MM, 18MM, etc. Your ol' Merc should use a 14MM plug.
 
Being an old guy, it would be tough for me to change but it sure seems logical to me that metrics would make everybody's life easier. To me, working with decimals is much easier than working with fractions.
JMHO
