An exbibyte (a contraction of exa binary byte) is a unit of information or computer storage, abbreviated EiB.

1 exbibyte = 2⁶⁰ bytes = 1,152,921,504,606,846,976 bytes = 1,024 pebibytes

The exbibyte is closely related to the exabyte, which can either be a synonym for exbibyte, or refer to 10¹⁸ bytes = 1,000,000,000,000,000,000 bytes, depending on context (see binary prefix).
