1 kg = 1,097,769,238,499,215,084,016,780,676,223 electrons.

Hi The_Ghost, I told Bert:

I don't agree with Kaluza's finite, curled spatial dimensions.
Instead, I see the number of dimensions going up with scale;
because the more one zooms out, the more he knows a priori.

And you replied: " Are we defining the kilogram or universe origins ? "

Both. Mass_Energy as the fifth spatial dimension ( with time as the first )
is easiest to see at the cosmic level ( as the guage of cosmological time );
specifically, the heat ( joules ), pressure ( pascals ) and density of the CMB.
But, at least in theory, the SI kilogram could be defined as
X number of oscillations of a laser, just like the first 4 spatial dimensions.
There would have to be some conversions and intensity controls.

You continued:

In any event, here's a practical problem. Suppose one had
a method of emitting a carbon atom once every femtosecond.
It would take approximately 19 years to accumulate 12 grams
(1 mole) of the stuff, and that's assuming something
doesn't get clogged, since solid carbon is also known
as soot.

There are proposals to define the SI kilogram in terms of
1,097,769,238,499,215,084,016,780,676,223 electron mass units, see:

WikiPedia.ORG/wiki/Kilogram#Fundamental-constant_approaches

So which is heavier ? electrons or carbon atoms ?

An atom laser is a Bose-Einstein system, nothing like soot ( or diamonds ),
and the beam would be wider than one atom.
A photon laser is near absolute zero, yet some can bore through thick steal.

P.S. I hope that last bit of " code " I posted ( on Planck's constant )
wasn't too much for you.
