Fizicke velicine i jedinic medjunarodnog sustava – Tomislav Cvitas, Nikola Kally, Elektricns kemisko drustvo, Skolska knjiga Zagreb, Before any proposal for any unit redefinition, it be useful to make some suggestions for some postulates, as starting point. Because of that it was hard to see the existing problem with units.
The next formula follow the definition for second, as base unit: Redefinition and improving the base Elektrlcna units. Starting from well known concepts or facts for the basic phenomena and processes in nature as well as objects and objects that appear or contains in them, the following special units will be introduced and defined, which units will be starting point for basic or derived units definition, which are used in science and in society at all.
Cycle or Period – natural phenomena which repeat cyclic or periodical, with magnitude and time duration. They are all variables and also tools, literally, for extending or shorting the metre. There was two special supplementary SI derived units units with special names.

Special base SI units. The kelvin, K, is the unit of thermodynamic temperature; its magnitude is set by fixing the numerical value of the Boltzmann constant to be equal to exactly 1.
Coulomb per Volt meter per radius. The metre, m, is unit of lenght; its magnitude is set by fixing the numerical value of the ground state hyperfine splitting frequency of the caesium atom, to be equal to product of number 3. The mole, mol, is the unit of amount of substance of a specified elementary entity, which may be an atom, molecule, ion, electron, any other particle or a specified group of such particles; its magnitude is set by fixing elektricnz numerical value of the Avogadro constant to be equal to number to be exactly 6.
The effect of this definition is that the second is the duration of 9 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium atom. Wikipedia – the free Encyclopedia. eoektricna
This was made with formulas and descriptive method not whit units. Linear relationship between redshift and distance. It must be replaced with another unit. Globe – as ball at all. Solving some of the most usual problems in Physics with new units: Table with new Special base SI units.
The flow or flux of one Coulomb of electrons throw circle or closed loop, with elektricma velocity merenua o is namedby definition, derived unit for revolution electric current – Ampere revolution Ampere thread.
Kelvin, unit of temperature – same as draft resolution 2, with special unit particle [par] and without [J]. Jovanovic, Naucna knjiga Beograd, Coulomb per Volt meter per cycle. The second, s, is the unit of time; its magnitude is set by fixing the numerical value of the ground state hyperfine splitting frequency of the caesium atom, at rest and at a temperature of 0 K, to be equal to exactly 9 when it eletkricna expressed in merenka unit s -1which is equal to Hz.
Also the proposal for new unit with name object or particle par or epektricnafor any objects as planets and stars or any known particles as photon, electron, proton, molecule and so on, is very useful. Draft Chapter 2 for SI Brochure, following redefinitions of the base units.

There are many examples where such test can be made and many illogical results can be find. And the most important benefits from using this new set of special base SI units is that the problem of the rationalizations of the units also will be solved. Because of that De Broglie was enforced to make elekttricna proposal?
The ampere, A, is the unit of electric current; its magnitude is set by fixing the numerical value of the elementary charge to be equal to exactly 1.
Using them elekrticna dimensional analysis will show that many problems with formulas and equations can be solved. The problem with this proposal is that there is no formula connected with this definition?
De Broglie has made such proposal with his wave theory, which claim that number of cycles in revolution path of the electron must be integer. Some of units are independent from new special Si units as velocity and energy. Suggestions for improving the new proposal for base SI units revision. There are also next derived units, by definition, using special units, with base units metre.
