In this paper, it is argued that the SI system has not carefully enough taken into account the differences that exist between stoichiometry and physics, and because of this neglect forced the kind-of-quantity amount of substance into a false form. The mole is not a unit such as the metre, the kilogram, and the second. It is a “unit” only in the sense in which purely mathematical scaling factors can be called units. 
Why dimensionless units should not be used in physics.
The quantities of dimension one - known as the dimensionless quantities - are widely used in physics. However, the debate about some dimensionless units is still open. The paper brings new
The Background and Implications of the "New SI" for Analytical Chemists
The International System of Units (SI) is not in itself a complete philosophical system; it has been developed over time to deal with practical needs. It started during the French revolution with
Alternative interpretations of the mole and the ideal gas equation
The fundamental concept of the mole stems from the idea of the gram-atom (or gram-molecule): that an amount of one mole of a given substance has an associated mass, in grams, numerically exactly
Constancy and Circularity in the SI
The International System of Units (SI) tries to find or construct something that does not change with time and place, since such constancy is the best possible ground for definitions of fundamental
The mole is an Avogadro number of entities, the macroscopic unit for chemical amount

Just as the gram is an Avogadro number of daltons, g = (g/Da) Da, the current definition of the mole can be interpreted as an Avogadro number of entities, as it is often thought of by chemists—and it
Looking back at two decades of “Metrology in Chemistry”
In this Editorial, I am announcing the end of my 16 years of formal responsibility for this Journal as I am becoming slightly subject to biological boundary conditions imposed by mother nature.
About continuity and discreteness of quantities: examples from physics and metrology
The VIM3 defines a quantity as a “property of a phenomenon, body, or substance”, leaving the characteristics of the term ‘quantity’, related to the chosen characteristics of the relevant properties.
Quantities, units and computing
The computer representation of quantities and SI units is reviewed at four levels; three implementations (languages, calculators and sensor data transfer) supporting units of measure are examined and some suggestions for a hierarchy of metrological-informatics standards are given.
A critical review of the proposed definitions of fundamental chemical quantities and their impact on chemical communities (IUPAC Technical Report)
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
Quantities as Metrical Coordinative Definitions and as Counts: On Some Definitional Structures in the New SI Brochure
The aim of the paper is to uncover never before presented definitional structures in the SI Brochure made by means of the two notions absolutely discrete quantities (counts) and metrical coordinative definitions.


Failures of the global measurement system. Part 1: the case of chemistry
This discussion puts a case of advocatus diaboli: that the Treaty of the Metre, its associated administrative apparatus and the International System of measurement units (SI) has basically failed for
Simple principles for metrology in chemistry: identifying and counting
We examine the problem of quantitative chemical measurement for well-identified substances, discuss the quantity called ‘amount of substance’, the means of expressing it, and its physical SI unit the
Metrological thinking needs the notions of parametric quantities, units and dimensions
The paper introduces a distinction between true metric and parametric quantities, units and dimensions. It claims in its first part that these distinctions shed important light both on the base
A skeptic’s review of the New SI
Proposals in draft form have been circulated for new Système International (SI) measurement units that are expected to be official instruments of the Treaty of the Metre by 2015. This review outlines
Integer numbers and their ratios are key concepts in describing the interactions of atoms and molecules
A general discussion of the redefinition of the mole, the SI unit for ‘amount of substance’, is now ongoing in ever broadening circles as part of a general overhaul of the Systeme International
The ontological distinction between units and entities
This paper argues that a clear and unambiguous scientific distinction should be made between measurement and enumeration, and examines confusion in metrological definitions and nomenclature concerning this distinction.
Numerosity versus mass
The particulate nature of matter was not evident for a long time in early history. Demokritos (460–370 BC) is mostly credited with the concept of particulate matter, probably based on philosophical
Theory and measurement
Measurement is fundamental to all the sciences, the behavioural and social as well as the physical and in the latter its results provide our paradigms of 'objective fact'. But the basis and
Failures of the global measurement system. Part 2: institutions, instruments and strategy
Between 1998 and 2007, the governing body of the Treaty of the Metre conducted three strategic reviews of future global measurement needs. This critical review examines those reports with a view to
