Description / Abstract:
This standard includes definitions for physical quantities and
units commonly used in applied science and technology, and related
terms that concern systems of measurement. Particular emphasis is
placed on the International System of Units (SI).
Purpose
IEEE Std 270-1966 attempted to cover not only quantities and
units, but also the much broader area implied in its title,
"General (Fundamental and Derived) Electrical and Electronics
Terms." This scope proved to be far too broad, and the standard
could not be maintained. The purpose of this revision is to present
authoritative definitions of physical quantities and units and
other terms relating to measurement systems, with particular
emphasis on the vocabulary used in IEEE/ASTM SI 10.
