Go read the definition of "arbitrary".
Then do some research into the how the length of the meter was derived and why.
It's like talking to a wall!
There's nothing special about 39.xx inches as the length for the meter. It could have been twice as long, or half as long, and worked out just as well. (the mass of a gram would change, of course)
And this is why is it arbitrary.
You didn't do the research, did you?
Like I said before, if it was arbitrary there would have been no reason whatsoever for having chosen 1/10,000,00 the distance from the NP to the equator. But there was. There were lots of reasons and the decision wasn't made by one man, it was made by a group of scientists. The decision was not made lightly.

kind of divining rod to locate the most expensive parts adjacent the
object we are trying to hit.

1/3 a millimeter = .0131233333333333 in inches and a meter is 13.123333333333333 inches
one reason we haven't switched, Is our machinery still have in cremates in inches .the modern machines are doing both. slow is best way to do this.
QuoteThey assumed the earth was perfectly round, which it isn't, and they were off on the length of a metre by 1/5 of a millimeter. That's .0002% of a metre. I did the calculation for you since it is so hard.
BTW, your math is wrong here.

It's comical seeing you continue to try to come up with reasons that this definition is meaningful. You said yourself, there was nothing special about 39.3 inches.
And it's not exactly the most useful definition out there - the marks on the platinum bar were much more convenient than having to remeasure from the pole to the equator (huge potential for error here)
QuoteQuoteThe point is the entire system is based upon one arbitrary metric, the number of digits on our hands, and the properties of water.
The American system is a collection of arbitrary measurements.
Oh? Really? Where's your metric time? Still 24 hours each made of 60 minutes each made of 60 seconds the last time I looked. What, exactly, makes radians superior? Just two examples.
You've been brainwashed into thinking it's a superior system when, in fact, it's just as arbitrary as anything.
The SI system only uses seconds, and standard multiples (MILLI, NANO, ETC). Minutes and hours are not SI units.
The SI system is superior because it is rational (in the technical sense).
Other everyday SI units we use are volts, amperes, and ohms. Anyone know the Imperial unit of electric current?

Having grown up with both, metric in incredibly easier to remember and work with. You get used to British, but people get used to daytime TV, too.

QuoteAs Bill said, it is based on a single arbitrary measurement. Rather than a whole rafterload of them.
oh, I don't discount the value of the intertwining units, particularly for science work.
But for daily life, the gains are minimal. The meter seems just as arbitrary as a foot, the kilo as a pound or stone, the kilometer versus the mile.
Biggest gain would be in cooking, where you could replace the ridiculous volume sizes teaspoon, tablespoon, peck, smidge, "measure", etc, though I believe the better cooks do it more by feel than by exact sizing.

QuoteRight. You don't have to say millimetre. You could say 'thousanth of a metre' (or 'thou' like people do for thousanth of an inch).
People rarely say gigagrams; they say tonnes.
OH YEAH, THAT'S EASIER. That would be like saying one-five thousand two hundred eightyeth of a mile instead of sayibg one foot.fiftySo instead of saying foot.

Yeah but at least I wouldn't have to guess anymore whether I should use volume or weight

QuoteUh huh . . . please divide a meter into exactly 3 equal parts.
1/3 a millimeter = .0131233333333333 in inches and a meter is 13.123333333333333 inches

And how would building trades deal with this?
Are all of our material dimensions going to have to change?
No more 2X4's, no 4X8 sheets of plywood. If I'm doing repairs on my old farm house will I have to buy metric sized materials and cut them down? Studs will go to half a meter on center?
You are correct. The metre is arbitrary. Nothing else in the metric system is. On the other hand the arbitrary units of the imperial system include the inch, foot, yard, mile, ounce, pound, ton, fluid ounce, cup, horsepower,.... the list goes on.
