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 related to the ambiguous exabyte, which officially means 10¹⁸ (1,000,000,000,000,000,000) bytes, but is commonly used to mean exbibyte.
