These new proposed base SI units definitions will enable determination of all known rest derived units and constants.

Metode i instrumentacija za električna merenja

Some of units are independent from new special Si units as velocity and energy. The problem with this definition is that the base unit for time, second, is determined by definition, equal to number of periods, not with formulae.

Before any proposal for any unit redefinition, it be useful to make some suggestions for some postulates, as starting point. But now with new proposed special base units this dilemma shall be solved and they are only derived units and used only for angle calculations not for velocity and similar equations, connected with them.

Cycle or Period – natural phenomena which repeat cyclic or periodical, with magnitude and time duration. Ampere is not unique unit, because depend of special units for velocity, and because of that also can’t be basic unit? Distance – as space between two points.

Radius – as element of the circle. The present basic unit of electric current Ampere can’t be basic unit because is defined with Coulomb. The present International System of units SI is not finished job. But if the units are chosen with wrong basic postulates than they can become main reason for stagnation or for developing of human knowledge.

If the equation for energy is express with special base units then next relations are valid. With this new proposal for special SI base units, for example, we can solve the existing problem with dimensions and units in well-known equation for the photon quantum energy, where are mix two units from different fields. 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 is expressed in the unit s -1which is equal to Hz.


There are seven principal SI base units in each of seven different categories. 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. It must be improved and developed in accordance with new theoretical research projects and also with new experimental equipments and techniques.

This proposal express with formulae. Jovanovic, Naucna knjiga Beograd, The flow or flux of one Coulomb of electrons throw radius as part of the circle or closed loop, with angular velocity w is namedby definition, derived unit for radius electric current – Ampere radius.

Suggestions for improving the new proposal for base SI units revision Aco Z. Elektricna merenja – V. 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.

It must be replaced with another unit. Fizikalne velicine i mjerne edinice SI – Dipl. 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.

The metre, m, is the unit of length; its magnitude is set by fixing the numerical value of the speed of light in vacuum to be equal to exactly when it is expressed in the unit m s They are universal and independent units. With this definition for second is hard to connect base unit metre with periods.


This was made with formulas and descriptive method not whit units. The kilogram, kg, is the unit of mass; its magnitude is set by fixing the emrenja value of the Planck constant to be equal to exactly 6. If we express this equitation with new special SI eleektricna units we shall get: 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.


For distances R larger than the radius of the Hubble sphere rHS objects recede at a rate faster than the speed of light??? Revolution – circle or any closed loop. Also the proposal for new unit with name object or particle par or obfor any objects as planets and stars or any known particles as photon, electron, proton, molecule and so on, is very useful.

Implementation of this redefined SI units, in present International System of Units SIwill improve the system, clear the most of the existing problems in science and also gave new approach and solution for many physical laws. Because the number of ekektricna electrons is taken as base to define the unit Coulomb, and with that the base unit Ampere, it be usefully to take also the number of the electrons as base, to define the basic unit kilogram.

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 the numerical value of the Avogadro constant to be equal to exactly 6.

This equation can’t be base for base unit definition for mass, kilogram [kg].
