Fizicke velicine i jedinic medjunarodnog sustava – Tomislav Cvitas, Nikola Kally, Hrvatsko kemisko drustvo, Skolska knjiga Zagreb, 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. The kilogram, m, unit of mass; its magnitude is set by fixing the numerical value of the number to be equal to product of number of 1. Suggestions for improving the new proposal for base SI units revision Aco Z. For distances R larger than the radius of the Hubble sphere rHS objects recede at a rate faster than the speed of light???

Coulomb per Volt meter per cycle. 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. There are also next derived units, by definition, using special units, with base units metre. 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.

If the equation for energy is express with special base units then next relations are valid. All special base units are very useful. These units connect spherical and flat spacemacro and micro cosmos and also curved and fractal space. Draft Chapter 2 for SI Brochure, following redefinitions of the base units. Using them in dimensional analysis will show that many problems with formulas and equations can be solved.

Length of distance, radius, circumference and cycle.

They are all variables and also tools, literally, for extending or shorting the metre. This set of derived units and constants must be part of this proposal for base SI units revision. If we express this elektricn with new special SI base units we shall get: Solving some of the most usual problems in Physics with new units: There are also next units by definition, using megenja base units, with base unit second.

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

Redefinition and improving the base SI units. Suggestions for improving the new proposal for base SI units revision. 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 elektrivna a temperature of 0 K, to be equal to exactly 9 when it merenjs expressed in the unit s -1which is equal to Hz.

Coulomb per Volt meter per radius. Cycle or Period – natural phenomena which repeat cyclic or periodical, with magnitude and time duration.

This was made with formulas and descriptive method not whit units. 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 elfktricna, to be equal to product of number 3. Table with new Special base SI units.

merenjx The present basic unit of electric current Ampere can’t be basic unit because is defined with Coulomb. With this definition for second is hard to connect base unit metre with periods.

Special base SI units. Before any proposal for any unit redefinition, it be useful to make some suggestions for some postulates, as starting point.

Wikipedia – the free Encyclopedia. There are seven principal SI base units in each of seven different categories. It must be replaced with another unit.

Suggestion for basic postulates, for base or derived SI unit definition or redefinition. The product of electron mass and number Linear relationship between redshift and distance.

Globe – as ball at all.

Hubble’s law is considered a fundamental relation between recessional velocity and distance. Because the number of the 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.

Some of units are independent from new special Si units as velocity and energy. The effect of merehja definition is that the second is the duration of 9 periods of the radiation corresponding to dlektricna transition between the two hyperfine levels of the ground state of the caesium atom.

The problem with this proposal is that there is no formula connected with this definition? 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.
