Three Masses

Masses

Mass References

Here are three special masses:

The Neutron-mass
The Planck-mass
The Standard SI-mass

Two are mine...

My Neutron Mass

Neutron Codata

Neutron Mass 1.67492729E-27 kg
I came up with this, derived on another page.

Compare Codata with my derived Neutron mass
Agreement out to eight places, (with my G)...

sub atomic size

Planck Mass

Planck Mass.
Planck Mass = 2.17651E-08 kg

illustrative purposes

An actual representation of this mass would be smaller than this.

My computer keeps giving me these "curiosity things". I wish to not put too much emphasis on it yet.

If you have read my other pages, you can see how this can easily happen to me. I cringe every time I turn on the computer. I am afraid I will get: "Cecil, Did you know...".

My Standard SI-Mass

Another mass: the "Standard SI-Mass"
Not to be confused with all of the standard brass weights.
I guess that I created this one too.
It is found no where else, except on my web site.
I Defined it as such:

Two point masses, SI kg-type,

Defining masses separated by one meter,

Producing one newton of force.

The SI Mass is the reciprocal of the square root of G.

for illustrative purposes only

Analogous to Coulombs law:
Two point charges, one "coulomb" each,
Defining charge separated by one meter
Producing one newton of force.

Standard SI Mass = 1.22411E+05 kg
26,9870 lbs
Approximately 12 tons

My standard mass has an interesting property...
Ratio of the square MassPlanck to MassStandard is hc/2pi.

Then he said to them, So give back to Caesar what is Caesar's, and to God what is God's.
