IEEE Standards Coordinating Committee 14
Letter Symbols for Units of Measurement
This site is maintained as the
public face of IEEE Standards Coordinating Committee 14, Letter Symbols for Units of Measurement (SCC 14). It has the following purposes:
Our work centers around the International System of units, sybmolized as SI. This is sometimes called the "modern metric system" or simply as the "metric system". By "metric system", the U.S. Government and IEEE mean the SI.
to keep those who are not members of
the working group informed on the group's mission and progress,
to provide for those who are not members
of the group a means of submitting comments and suggestions, and
to provide an avenue for members of
the group to reach the group's private work area.
This site represents a small group, many of whom are volunteers, working together
to achieve consensus. The specifics of our work should be expected to change
from time to time. We monitor changes in the SI, as promulgated by the CIPM/BIPM, activities of other standards generating organizations (NIST, ISO, IEC, etc.). We track the progess of metric education in U.S. schools and progress toward full metrication by the U.S. Government and state governments. And we react accordingly in carrying out our efforts. This material
is copyrighted by IEEE and all rights are retained by the IEEE.
Assist other IEEE working groups and SCCs in properly using the SI in IEEE standards and other documents.
Review proposed IEEE Standards and revisions to those standards to assure proper use of the SI and as part of that process to cast a coordination ballot as part of the approval process.
Represent the IEEE as part of the Joint Committee responsible for maintaining the American National Standard for Use of the International System of Units (SI): The Modern Metric System (IEEE/ASTM SI 10-2002)
Maintain the standards for which this committee is responsible, namely:
- IEEE Standard Letter Symbols for Units of Measurement (SI Customary Inch-Pound Units, and Certain Other Units), IEEE Std 260.1-2004 (due for reaffirmation or revision in 2009)
- American National Standard Mathematical Signs and Symbols for Use in Physical Sciences and Technology, IEEE Std 260.3-1993 (reaffirmed 2006)
- American National Standard Letter Symbols and Abbreviations for Quantities Used in Acoustics, IEEE Std 260.4-1996 (reaffirmed 2006)
- IEEE Standard Definitions for Selected Quantities, Units, and Related Terms, with Special Attention to the International System of Units (SI), IEEE Std 270-2006
- IEEE Standard Letter Symbols for Quantities Used in Electrical Science and Electrical Engineering, IEEE Std 280-1982 (extended pending development of proposed standard 80000)
- IEEE Recommended Practice for Preferred Metric Units for Use in Electrical and Electronics Science and Technology, IEEE Std 945-1984
- IEEE Standard for Prefixes for Binary Multiples, IEEE Std 1541-2002 (reaffirmed 2008)
- Standard for Quantities and Units, P80000 (in development)
- IEEE/ASTM Standard for Use of the International System of Units (SI): The Modern Metric System, IEEE/ASTM SI 10-2002 (revision in progress)
The committee does most of its work by means of electronic and telephonic communication. We hold annual face-to-face meetings with conference call capability for members who cannot physically attend. The next meeting will be held:
2009 April 23
NIST Headquarters, Gaithersburg MD
The IEEE/ASTM Joint Committee for Maintaining SI 10 will meet following the above SCC 14 meeting and in the same location.
Comments from the public are welcomed.
The committee's maillist is closed in order to allow private group discussion, but suggestions
and comments from the public will be cross-posted by the chair if the originator
desires. If you wish to have your suggestion or comment forwarded to the
group please send an e-mail message to the chair at firstname.lastname@example.org.
Ensure that you explicitly state "please
post" or "please forward"
in the text of your message. Otherwise, your communication will be considered
This area is provided to permit
the working group a private area in which to work privately. The public
has opportunity provided above by which to comment. Also, the working group's
finished draft with the proposed changes will undergo the normal IEEE procedures
for public comment and voting. This area is password-protected and may
be accessed by clicking here
