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 this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 80000-3 was prepared by Technical Committee ISO/TC 12, Quantities, units, symbols, conversion factors,
in collaboration with IEC/TC 25, Quantities and units, and their letter symbols.
This first edition cancels and replaces the second edition of ISO 31-1:1992 and of ISO 31-2:1992. The major
technical changes from the previous standards are the following:
— the presentation of numerical statements has been changed;
— the remark on logarithmic quantities and their units in the Introduction has been changed;
— the normative references have been changed;
— the quantities radial distance, position vector, displacement and rotation have been added to the list of
quantities.
ISO 80000 consists of the following parts, under the general title Quantities and units:
— Part 1: General
— Part 2: Mathematical signs and symbols for use 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
IEC 80000 consists of the following parts, under the general title Quantities and units:
— Part 6: Electromagnetism
— Part 13: Information science and technology
— Part 14: Telebiometrics related to human physiology

Introduction
0.1 Arrangement of the tables
The tables of quantities and units in this International Standard are arranged so that the quantities are
presented on the left-hand pages and the units on the corresponding right-hand pages.
All units between two full lines on the right-hand pages belong to the quantities between the corresponding full
lines on the left-hand pages.
Where the numbering of an item has been changed in the revision of a part of ISO 31, the number in the
preceding edition is shown in parenthesis on the left-hand page under the new number for the quantity; a dash
is used to indicate that the item in question did not appear in the preceding edition.
0.2 Tables of quantities
The names in English and in French of the most important quantities within the field of this International
Standard are given together with their symbols and, in most cases, their definitions. These names and symbols
are recommendations. The definitions are given for identification of the quantities in the International System of
Quantities (ISQ), listed on the left-hand pages of the table; they are not intended to be complete.
The scalar, vectorial or tensorial character of quantities is pointed out, especially when this is needed for the
definitions.
In most cases only one name and only one symbol for the quantity are given; where two or more names or two
or more symbols are given for one quantity and no special distinction is made, they are on an equal footing.
When two types of italic letters exist (for example as with ϑ and θ; ϕ and φ; a and a; g and g) only one of these
is given. This does not mean that the other is not equally acceptable. It is not recommended to give such
variants different meanings. A symbol within parenthesis implies that it is a reserve symbol, to be used when, in
a particular context, the main symbol is in use with a different meaning.
In this English edition, the quantity names in French are printed in an italic font, and are preceded by fr. The
gender of the French name is indicated by (m) for male and (f) for female, immediately after the noun in the
French name.
0.3 Tables of units
0.3.1 General
The names of units for the corresponding quantities are given together with the international symbols and the
definitions. These unit names are language-dependent, but the symbols are international and the same in all
th 1)
languages. For further information, see the SI Brochure (7 edition 1998) from BIPM and ISO 80000-1 .
The units are arranged in the following way.
a) The coherent SI units are given first. The SI units have been adopted by the General Conference on
Weights and Measures (Conférence Générale des Poids et Mesures, CGPM). The use of coherent SI units

is recommended; decimal multiples and submultiples formed with the SI prefixes are recommended even
though not explicitly mentioned.
b) Some non-SI units are then given, being those accepted by the International Committee for Weights and
Measures (Comité International des Poids et Mesures, CIPM), or by the International Organization of Legal
Metrology (Organisation Internationale de Métrologie Légale, OIML), or by ISO and IEC, for use with the SI.
Such units are separated from the SI units in the item by use of a broken line between the SI units and the
other units.
c) Non-SI units currently accepted by the CIPM for use with the SI are given in small print (smaller than the text
size) in the “Conversion factors and remarks” column.
d) Non-SI units that are not recommended are given only in annexes in some parts of this International
Standard. These annexes are informative, in the first place for the conversion factors, and are not integral
parts of the standard. These deprecated units are arranged in two groups:
1) units in the CGS system with special names;
2) units based on the foot, pound, second, and some other related units.
e) Other non-SI units given for information, especially regarding the conversion factors, are given in another
informative annex.
0.3.2 Remark on units for quantities of dimension one, or dimensionless quantities
The coherent unit for any quantity of dimension one, also called a dimensionless quantity, is the number one,
symbol 1. When the value of such a quantity is expressed,
