What is ISO 80000-2 - quantities and units of mathematics about?
ISO 80000 comprises a series of international standards introducing the International System of Quantities. The guidelines of the ISO 80000 family of standards specify the use of physical quantities and units of measurement, along with the related formulas and units, in scientific and educational documents.
ISO 80000-2 specifies mathematical symbols, explains their meanings, and gives verbal equivalents and applications. ISO 80000-2 is intended mainly for use in the natural sciences and technology, but also applies to other areas where mathematics is used.
Who is ISO 80000-2 - quantities and units of mathematics for?
ISO 80000-2 on quantities and units of mathematics has applications for education and research in the fields of:
- Mathematics
- Physics
- Chemistry
- Earth science
- Astronomy
- Technology
- Biology
Why should you use ISO 80000-2 - quantities and units of mathematics?
The availability of standardized measurements across the sciences and nationalities facilitates research, education, and knowledge expansion. The tables of symbols and expressions in ISO 80000-2 give hints about the meaning or how the expression may be read for each item of the symbol under consideration, usually in the context of a typical expression. The purpose of the entries is the identification of each concept, and is not intended to be a complete mathematical definition.
ISO 80000-2 also gives the symbols of coordinates, as well as the position vectors and their differentials, for coordinate systems in three-dimensional spaces.
The guidelines of ISO 80000-2 provide you with required symbols, their meanings and application of mathematics to facilitate research and education.
