IEC 60027

From Free net encyclopedia

IEC 60027 (formerly IEC 27) is the International Electrotechnical Commission's standard on Letter symbols to be used in electrical technology. It consists of several parts:

IEC 60027-1: General
IEC 60027-2: Telecommunications and electronics
IEC 60027-3: Logarithmic and related quantities, and their units
IEC 60027-4: Symbols for quantities to be used for rotating electrical machines
IEC 60027-6: Control technology
IEC 60027-7: Physiological quantities and units

A closely related international standard on quantities and units is ISO 31.

Binary prefixes

Template:Main A 1999 addendum to IEC 60027-2 on binary prefixes has resulted in some public interest in the standard and is still being widely discussed in the computer community, as it attempts to finally settle the confusion about whether a kilobit corresponds to 1000 bits or 1024 bits.
