Kilobytes (KB)

Definition

A kilobyte (KB) is a decimal unit of digital information equal to 1,000 bytes, as defined by the International System of Units (SI). It should not be confused with the kibibyte (KiB), which equals 1,024 bytes.

History

The kilobyte emerged in the early days of computing. Initially, it was informally used to mean 1,024 bytes (2¹⁰), but the IEC standardized the distinction in 1998, reserving 'kilobyte' for 1,000 bytes and introducing 'kibibyte' for 1,024 bytes.

Current use

Kilobytes are used by storage manufacturers and telecom standards to express small file sizes, cache sizes, and data transfer quantities using the decimal (SI) convention.

Kibibytes (KiB)

Definition

A kibibyte (KiB) is a binary unit of digital information equal to 1,024 bytes (2¹⁰ bytes). It was introduced by the IEC to distinguish from the decimal kilobyte (1,000 bytes).

History

The kibibyte was standardized by the International Electrotechnical Commission (IEC) in 1998 as part of a set of binary prefixes (kibi-, mebi-, gibi-, tebi-) to eliminate the ambiguity between decimal and binary interpretations of data units.

Current use

Kibibytes are used in operating systems, programming, and technical specifications where exact binary sizes matter — such as memory allocation, page sizes, and kernel-level storage reporting.
