“…Currently, the mole is defined as being that amount of substance which contains as many elementary entities as there are atoms in 0.012 kg of carbon-12 [61]. The number of entities in one mole of substance is related to the Avogadro constant that is in essence a scaling factor between macroscopic and microscopic, particulate quantities [60,62,63].…”

Abstract:In the proposed new SI, the kilogram will be redefined in terms of the Planck constant and the mole will be redefined in terms of the Avogadro constant. These redefinitions will have some consequences for measurements in chemistry. The goal of the Mole Project (IUPAC Project Number 2013-048-1-100) was to compile published work related to the definition of the quantity 'amount of substance', its unit the 'mole', and the consequence of these definitions on the unit of the quantity mass, the kilogram. The published work has been reviewed critically with the aim of assembling all possible aspects in order to enable IUPAC to judge the adequateness of the existing definitions or new proposals. Compilation and critical review relies on the broadest spectrum of interested IUPAC members.

“…• Complexity, incomprehensibility to users, unteachability and incommunicability [16][17][18][19][20][21][22][23][24]. • Lack of robustness, relevance, practicality and adaptability in a closed and irreversible system [17,[19][20][21][22].…”

“…The resolve of the proponents of the new SI to ignore or misrepresent those concerns is disturbing indeed and is raising serious questions regarding governance of the Treaty of the Metre. The March issue of this journal, ACQUAL [15], in many articles, raised many questions concerning the treatment of chemical measurements and the principles of the new SI [16][17][18][19][20][21][22][23][24]. None have been convincingly addressed by the proponents of the new SI, despite repeated invitations to do so.…”

“…It is a particular obsession of the International Committee on Weights and Measures (CIPM) and its Consultative Committee on Units. It has not been justified or argued for, it has been assumed as a physicists' imperative without regard for the fundamental purposes of a system of measurement units or the basic principles of practical measurement system design [23].…”

A recent discussion by Martin Milton in the November issue of this journal was critical of many published objections to the proposed new International System (SI) measurement units (and in particular the definition of the mole) on the grounds that many objectors had proposed new terms in attempts to clarify thinking and that it is impractical to achieve consensus on such proposals. This discussion in response argues that those criticisms miss the point of the objectors' arguments and are perhaps more appropriately directed at both the current and the new SI itself. A primary example of a neologism in the SI is the term ''amount of substance.'' The many substantive problems with the new SI remain unaddressed by its proponents. Many important consequences of exactly fixing multiple inter-dependent fundamental physical constants as the basis of the world's measurements would appear not to have been considered by the global institutions responsible for the world's measurement units.
