“…To this date the Kilogram is an artefact, and equal to the mass of the international prototype; however, the levitation balance and W att balance [11] clearly show th a t even heavy mass can be measured in terms of counting flux quanta $ 0. We suggest th a t from the many possible combinations of fundamental constants suggested [12], the set flux quantum and electron charge [$0,e] should be chosen as the (complete) basis of both the mechanical and electromagnetic units.…”

A b str a c t. T he understanding of electrom agnetic phenom ena is based on th e historic landm ark A Treatise on Electricity & M agnetism of 1873 by Jam es Clerk Maxwell. T he form in which th e theory is m ost com monly expressed is in th e form of th e vector equations introduced by Gibbs. T here is another m ore general form ulation due to Elie C artan , in term s of external differential forms. We will develop the description of electrom agnetic phenom ena using these concepts. It is a pre-m etric description of conservation laws, th a t will highlight th e basic properties of th e electrom agnetic phenom ena. We will in p articu lar d em onstrate th e fundam ental role of th e flux quantum $ 0 = h /2 e , and point to ways to calibrate m agnetic fields.

“…With these established electrical units and scales of measurement, the unit of current, the ampere, as well as the units of energy and power-joule and wattare easily realized. It's only when these ''derived'' units are available, that a mise-en-pratique or realization of the real unit of mass via the watt experiment [22] is possible.…”

The International System of Units (SI) follows a concept that goes back to Maxwell. At that time, a logic sound foundation of mathematics was not yet available. This has lead to concepts and terms that are contradictory and in conflict with today's standard mathematical concepts. The inconsistencies that have evolved in metrology due to the lack of appropriate notions are pointed out. This is most important, as the metrology is a field that is internationally well organized under the umbrella of the Meter Convention, an international treaty for acting on all matters relating to units of measurement. Committees and working groups under the Meter Convention have a leading role in the elaboration of important metrological guides, among others the International Vocabulary of Metrology. Therefore, it is highly desirable that their publications use well-founded concepts and terminology. It is consensus that it is desirable to find a system of units on invariant properties of nature and not on human artifacts, e.g., the prototype of the kilogram. However, the current proposals to improve that are in conflict with standard scientific concepts. It is shown in the paper how these inconsistencies can be avoided. The argumentation is based on the interpretation of numbers developed by mathematicians like Cantor, Dedekind, Peano, and others that have led the logic foundation of mathematics with set and number theory. This foundation excludes dogmas that have been forwarded in the last century under the umbrella of the Meter Convention.
