Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of ISO 80000-1 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 80000-1 was prepared by Technical Committee ISO/TC 12, Quantities and units in co-operation with
IEC/TC 25, Quantities and units.
This first edition of ISO 80000-1 cancels and replaces ISO 31-0:1992 and ISO 1000:1992. It also incorporates
the Amendments ISO 31-0:1992/Amd.1:1998, ISO 31-0:1992/Amd.2:2005 and ISO 1000:1992/Amd.1:1998.
The major technical changes from the previous standard are the following:
⎯ the structure has been changed to emphasize that quantities come first and units then follow;
⎯ definitions in accordance with ISO/IEC Guide 99:2007 have been added;
⎯ Annexes A and B have become normative;
⎯ a new normative Annex C has been added.
ISO 80000 consists of the following parts, under the general title Quantities and units:
⎯ Part 1: General
⎯ Part 2: Mathematical signs and symbols to be used in the natural sciences and technology
⎯ Part 3: Space and time
⎯ Part 4: Mechanics
⎯ Part 5: Thermodynamics
⎯ Part 7: Light
⎯ Part 8: Acoustics
⎯ Part 9: Physical chemistry and molecular physics
⎯ Part 10: Atomic and nuclear physics
⎯ Part 11: Characteristic numbers
⎯ Part 12: Solid state physics

Introduction
0.1 Quantities
Systems of quantities and systems of units can be treated in many consistent, but different, ways. Which
treatment to use is only a matter of convention. The presentation given in this International Standard is the
one that is the basis for the International System of Units, the SI (from the French: Système international
d’unités), adopted by the General Conference on Weights and Measures, the CGPM (from the French:
Conférence générale des poids et mesures).
The quantities and relations among the quantities used here are those almost universally accepted for use
throughout the physical sciences. They are presented in the majority of scientific textbooks today and are
familiar to all scientists and technologists.
1)
NOTE For electric and magnetic units in the CGS-ESU, CGS-EMU and Gaussian systems, there is a difference in
the systems of quantities by which they are defined. In the CGS-ESU system, the electric constant ε (the permittivity of
vacuum) is defined to be equal to 1, i.e. of dimension one; in the CGS-EMU system, the magnetic constant µ
(permeability of vacuum) is defined to be equal to 1, i.e. of dimension one, in contrast to those quantities in the ISQ where
they are not of dimension one. The Gaussian system is related to the CGS-ESU and CGS-EMU systems and there are
similar complications. In mechanics, Newton’s law of motion in its general form is written F = c⋅ma. In the old technical

system, MKS , c = 1/g , where g is the standard acceleration of free fall; in the ISQ, c = 1.

The quantities and the relations among them are essentially infinite in number and are continually evolving as
new fields of science and technology are developed. Thus, it is not possible to list all these quantities and
relations in this International Standard; instead, a selection of the more commonly used quantities and the
relations among them is presented.
It is inevitable that some readers working in particular specialized fields may find that the quantities they are
interested in using may not be listed in this International Standard or in another International Standard.
However, provided that they can relate their quantities to more familiar examples that are listed, this will not
prevent them from defining units for their quantities.
Most of the units used to express values of quantities of interest were developed and used long before the
concept of a system of quantities was developed. Nonetheless, the relations among the quantities, which are
simply the equations of the physical sciences, are important, because in any system of units the relations
among the units play an important role and are developed from the relations among the corresponding
quantities.
The system of quantities, including the relations among them the quantities used as the basis of the units of
the SI, is named the International System of Quantities, denoted “ISQ”, in all languages. This name was not
used in ISO 31, from which the present harmonized series has evolved. However, ISQ does appear in
[8]
ISO/IEC Guide 99:2007 and in the SI Brochure , Edition 8:2006. In both cases, this was to ensure
consistency with the new Quantities and units series that was under preparation at the time they were
published;
