Reaffirmed 2008. Names and letter symbols for prefixes that denote multiplication of a unit by the binary multiplier 2 10 n ,where n =1,2,3,4,5,or 6 are defined. Although the prefixes may be used with all units in all fields where multiplication by a binary multiplier is found to be appropriate, their primary use is in the field of information technology.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
P260.1
IEEE Draft Standard Letter Symbols for Units of Measurement (SI Units, Customary Inch-Pound Units, and Certain Other Units)
Letter symbols and corresponding units for SI and other common measurement units are covered in this standard.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
1541-2021
IEEE Standard for Prefixes for Binary Multiples
Names and letter symbols for prefixes that denote multiplication of a unit by the binary multiplier 2 10n, where n = 1, 2, 3, 4, 5, 6, 7, or 8 are defined. Although the prefixes may be used with all units in all fields where multiplication by a binary multiplier is found to be appropriate, their primary use is in the field of information technology.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
260.1-2004
IEEE Standard Letter Symbols for Units of Measurement (SI Customary Inch-Pound Units, and Certain Other Units)
Revision of IEEE Std 260.1-1993, Letter symbols for units of measurement are covered in this standard.
280-1982
IEEE Standard Letter Symbols for Quantities Used in Electrical Science and Electrical Engineering
Letter symbols used to represent physical quantities in the field of electrical science and electrical engineering are defined. The symbols are independent of the units employed or special values assigned. Also included are selected symbols for mathematics and for physical constants.
