TS EN IEC 80000-13

TS EN IEC 80000-13 is the Turkish-adopted version of the standard that organises the names, symbols and definitions of quantities and units used in information science and technology. It provides a shared terminology for numerical information, data size, data rate and related technical quantities, helping the same concepts be used consistently across documents, equipment and software contexts.

A common language for quantities in information technology

In general technical context, the standard helps distinguish the quantity being described from the unit used to express it. That distinction is especially important in information science and technology, where terms such as bit, byte, bit rate and data capacity are often used interchangeably in everyday language. Standards of this type support consistent use in technical documentation, device labelling, software interfaces and descriptions of data communication.

Binary prefixes and conversion guidance

This edition of IEC 80000-13 gives names and symbols for the relevant quantities and units, and where appropriate it also provides conversion factors. It further includes prefixes for binary multiples, which is particularly useful when distinguishing between decimal-based and binary-based expressions in areas such as memory and storage capacity. Compared with the previous edition, the standard has been technically revised with the addition of new binary prefixes.

• Names and symbols for quantities and units
• Definitions used in information science and technology
• Conversion factors where appropriate
• Prefixes for binary multiples

As a result, the standard does more than define vocabulary: it establishes a consistent technical framework for expressing quantities in information technology in a way that is clear and comparable. Its scope is limited to terminology and unit-related conventions in this field, and it is intended to be read alongside the broader principles of the quantity and unit system.
