About This Item
TS EN ISO 80000-1 brings together the basic concepts used in the field of quantities and units: quantities, systems of quantities, units, quantity symbols, unit symbols, and coherent systems of units. It provides a shared conceptual framework for understanding the International System of Quantities (ISQ) and for interpreting how quantities should be named and represented across science and engineering.
How the core terminology fits together
In general technical use, a quantity is a property that can be measured or characterised, while a unit provides the reference needed to express that quantity numerically. A system of quantities organises related quantities into a consistent structure, and a coherent system of units ensures that derived units are formed in a way that remains compatible with the base units. This standard helps align those concepts so that symbols, terms, and notations are used consistently.
Scope and boundaries of the document
The information and definitions are intended for general use across the various fields of science and technology and serve as an introduction to the other parts of ISO 80000. The scope also states that the ISO/IEC 80000 series does not yet cover ordinal quantities and nominal properties, so the document should not be read as extending to those categories. It is a foundational reference for measurement language, calculation, and technical documentation.
