TS 298

TS 298 is a standard dealing with mathematical signs and symbols used in physics and technology within the SI system of units. This kind of notation forms part of the common language of science and engineering, helping quantities, equations, and technical statements be written and read consistently.

SI notation and consistency in technical writing

In general technical practice, SI-related signs and symbols influence how unit names, prefixes, multiples, fractions, and equation notation are presented. Standards in this area help improve legibility, reduce ambiguity across disciplines and languages, and support a consistent expression of quantities in measurement, calculation, and technical documentation. That broader context is especially important in science, engineering, and data presentation.

What this standard covers

The stated scope of this document is the mathematical signs and symbols included in SI and used in the physical sciences and technology. Its focus is therefore the naming and use of notation in those domains, rather than the physical units themselves. This record does not establish the individual symbols or formatting rules clause by clause, but it does identify the standard as a reference for the shared mathematical language used alongside SI.

This TS listing is withdrawn and was published as equivalent to ISO 31-11:1992. As a result, it is mainly useful for understanding historical SI notation practice and for interpreting legacy technical documents that still reflect that vocabulary and symbol set.
