What is one kilo.

What is the difference between 1dm³ and one decilitre?... is there any difference?.
I believed that a litre was a cubed meter of water measurement, therefore, a decilitre, being one tenth of a litre, was equivalent to one Decimetre [Dm] cubed?..

And yeah, 4degC, its "about" the same as melting ice water?..

and this is why us Yanks continue to regard the metric system as being silly and pretentious. not to mention inconvenient.

handy for scientists who are bad at maths. but consider: a pint is defined as the proper size serving of beer. (ale/lager/bitters/etc)

You need a standard that can actually be measured and compared to your unknown. Who's going to count silicone atoms?

Yes. I know the definition of a meter. But you actually can measure the wavelength of light. It's a little harder to say, OK, here is 10^XXsilicone atoms. They have to be in some form like a cube of silicone and then you're back to where we are now. You can't just count out that many atoms and put them on a scale.

The problem with using the speed of light to define length (a meter) is that you now have your standard for how long a meter is tied to a time standard. You better have a darn accurate clock if you want an accurate meter.

May I refer you to our learned Friend, the one who's job it is to know many things about water...



I totally agree.

Question, one cubic meter of water, yes, one ton, but, you say
after saying it was "define as 1dm3 of pure water at 4 degrees centigrade", so either both of us got it wrong, being they are the same, and what is the difference between a duck and all that ^{one of its legs is both the same} or I am confused..

Last time I checked a decilitre is one tenth of a litre of water. so my understanding is, I got it wrong, and its one tenth of a cubed meter of water, which is one demi-meter, one tenth of a cubed meter of water, which is just one Litre, so why the hell didnt they just say "One litre" of water on that program I was watching instead of saying one tenth of a ten gallon jug kind of extra detail confusing thing.

Yeah, Confused, Which to be honest, when it comes to them decimals, I am anyway.
I is too old for all this dessicated coconut thing.
They spent my whole school life teaching me imperials and then decided we should use "Something else instead"
Which leads to the issue in an engineering works somewhere with very fast jets where one "young" engineer was asked to measure a certain shaft from an engine part and transfer that to the one being made [by him] on the lathe.
He was handed a vernier gauge.
"I cant use this, its in imperial...."
Can anyone answer what the difference is between two shafts made to tolerances of one thou in either metrics of imperious?.. do it matter is it is "Exactly the same" in thousands of an inch or exactly the same in thousandths of a millimetre?.. the tolerance is less width than a human hair, dont care how you get there, it has to be "Exactly the same", but dont measure across the worn out bit which is why its being re-made.

Back to our jug of water....
{ I have tan/squared/cubed a bit here }

And maybe thats exactly what is the confusing bit... we were asked to change to a system that no one uses.


Up to the paint mark on a certified measured jug...
Yep, Pint comes from Paint.



Someone IS doing the work on a certified number of atoms, of a material that doesnt degrade, and is hard enough to not be worn by the handling required to measure it.
This is why the GK is loosing weight... despite the thing sitting under three glass domes in its housing, every time it is handled to make a clone, it gets worn.


The other problem {one of many} is that enter a huge gravitational force, and light is known to "slow down"....

The definition of the kilometre was set as the distance between two points on earth divided by one thousand.
Problem.
Enter Continental drift....

The point is that the metric system was "supposed" to replace a lot of local different measures, and whereas, we all agreed in the start that one grain of what equalled one Gram, where is the constant?.
Weight that gram again in two weeks in a dry grain store where the Rh has dropped from 80% to 30%, and then compare it against a slightly modified "Better" evolved breed of wheat.

It was supposed to be "Infallible", and all it has gone on to prove is that its all, as Einstein would say _{[thanks geezer...]} is that its all "Relative".

So I ask again, dependant on where you are stood, on top of Everest, or down the deepest gold mine in Africa, what is one kilogram.

However....

Take that same kilogram and a set of balance scales. Not a set of "Monumentally accurate" electronic scales, a set of balance scales.
Weigh out a measure of grain that is equal to that kilogram, and take that anywhere you want, and it will still "balance" exactly the same?...

So are we getting to "Technical" in what we are trying to do?.
Did the early Egyptians, and all others throughout history, who have used the balance scales, get it "Right on the money" right there and right then?...

Therefore, the old ways are the best.
Now excuse me I want to go get a cup of coffee... in my Pint Mug....
I dont care how many kilo-whatsits you want to say is in there, its still one cup of coffee... MY cup of coffee... and I will defend it to the last minion....

Yes if it was a measure of weight it would be measured in Newtons, you are correct.

I own an ancient torque wrench I use for my car which has a scale in "Kilopond". I am not sure how the scale translates the torque applied to lug nuts but using a modern wrench, I know how much 110N/m is and I doubt that my wheels fall off when I get too far away from Paris. It works and has the perfect size for handling rusty bolts changing a wheel and it perfectly fits into the gap between the trunk floor and the central locking vacuum pump of my car - or used to since my current car still has the compartment but no pump, it's the "decentral locking" version of the original Passat 35i I keep buying for over 20 years now.

Black people like them too.
