This document gives general information and definitions concerning quantities, systems of quantities, units, quantity and unit symbols, and coherent unit systems, especially the International System of Quantities (ISQ). The principles laid down in this document are intended for general use within the various fields of science and technology, and as an introduction to other parts of this International Standard. The ISO\/IEC 80000 series does not, as yet, cover ordinal quantities and nominal properties.<\/p>\n

A set of quantities and their relations are called a system of quantities. General Quantitiesquantities are related through equations that express laws of nature or define new general quantities. Each equation between quantities is called a quantity e…
It is convenient to consider some quantities of different kinds as mutually independent. Such quantities are called base quantities. Other quantities, called derived quantities, are defined or expressed in terms of base quantities by means of equations.
It is a matter of choice how many and which quantities are considered to be base quantities. It is also a matter of choice which equations are used to define the derived quantities. Each set of non-contradictory equations between quantities is called …
