So the kilogram is based upon a physical object the "platinum iridium cylinder" the only problem is that it changes weight overtime, therefore not having a true definition. the science community has now created the worlds roundest object the "Silicon Sphere" which only has "1 isotope of silicon" (silicon 28).. Which makes calculating the diameter & volume easier, which will allow us to move away from a physical object for a definition. So with D = the density of atoms .... V= πd to the 3rd power/6 .. Will hopefully be the set formula.
