exbibyte

An exbibyte (EiB) is a unit of digital information storage equal to 2^60 bytes, or 1,152,921,504,606,846,976 bytes. It is part of the IEC binary prefixes, which also include kibibyte (KiB) and pebibyte (PiB).

One exbibyte equals 1,024 pebibytes (PiB), and one pebibyte equals 2^50 bytes. In decimal terms, this is approximately 1.1529 × 10^18 bytes, so 1 EiB is about 1.1529 exabytes (EB).

Usage: EiB is used to express large data sizes in contexts preferring binary prefixes, such as computer memory or storage capacities in hardware documentation and technical contexts. Because the exabyte (EB) in decimal notation refers to 10^18 bytes, EiB and EB can differ significantly in value when discussing large data sizes.

Related units include kibibyte, mebibyte, gibibyte, tebibyte, pebibyte, and exabyte.
