The mass value is one when?

[Diamonds]

Is there an Universal mass that represents value 1 or one. If there is such a mass it must be one of the particles that exists and are known to us. 

An Electron is the first particle that occurs in my mind.  But its mass is 0.511 not one. But why not to think then that Two different electrons are allways joined together many ways and TWO Electrons are the universal mass representing as value 1 or one. 

E = mc^2 

m = 1 = 2 electrons

m = 1/2 = 1 electron

How can two separate particles that neglect each other be considered as to create this universal mass which value is as one.

Has the nature made it impossible that there ever exists the mass which value is exactly as one.

Are there ways that two electrons belongs together somehow? This I must find out first. 

Entanglement, spin ????? 

Now this idea may be a ridiculous but anyway I feel need to find out if any mass can be considered as being in all cases one in E = mc^2.

Of course if you feel that any 1 kg mass will do then do not answer pointing out that. It is not what I am seeking.

No, to your question but there is something even better!

Max Planck introduced what became later known as the Planck constant. At the end of the paper, he proposed the base units that were later named in his honor. The Planck units are based on the quantum of action, now usually known as the Planck constant, which appeared in the Wien approximation for black-body radiation. Planck underlined the universality of the new unit system, writing:

...” it is possible to set up units for length, mass, time and temperature, which are independent of special bodies or substances, necessarily retaining their meaning for all times and for all civilizations, including extraterrestrial and non-human ones, which can be called "natural units of measure".

While the values of Planck units are not 1, they are based only on the universal constants G , h, c and kB His definitions differ from the modern ones by a factor of 2 π because the modern definitions use ℏ [hbar ] rather than h .

I believe this is as close as you will come to finding a Universal Mass, as well as a Universal length, and many other Universal Units. Although their values are not One, they possess even more remarkable traits!

Since the Planck units are defined exclusively in terms of four universal physical constants: c, G, ħ, and kB; Expressing one of these four physical constants in terms of Planck units yields a numerical value of 1.

They are a system of natural units, defined using fundamental properties of nature (specifically, properties of free space) rather than properties of a chosen prototype object. Originally proposed in 1899 by German physicist Max Planck, they are relevant in research on unified theories such as quantum gravity.
