Revision Standard - Superseded.
In this period of transition, authors and editors of scientific and engineering literature sometimes need basic information on the International System of Units (the Metric System), described in this standard. This contains the units, supplementary units, and multiplier prefixes of the International System, along with instructions for their correct use. Numerous examples are given. Conversions between the International and the British-American System are also discussed, and a procedure is described for rounding after such conversions. Three appendixes define the International System base units, list conversion factors, and explain the work of the International Bureau of Weights and Measures.

The recommendations contained in this document are based upon the following premises, which are believed to represent the broadest base of general agreement among proponents of the major unit systems: (1) That for most scientific work and technical work of an analytic nature the International System of Units (officially designated SI)1 is generally superior to other systems; that this is particularly true for the fields of electrical science and technology since the common electrical units (ampere, volt, ohm, etc) are included among the SI units; that the International System of Units is more widely accepted than any other as the common language in which scientific and technical data ought to be expressed
