Exbibyte

The exbibyte is a multiple of the unit byte for digital information. It is a member of the set of units with binary prefixes defined by the International Electrotechnical Commission (IEC). Its unit symbol is EiB.

The prefix exbi (symbol Ei) represents multiplication by 2⁶⁰, therefore:

1 exbibyte = 2⁶⁰ bytes = 1152921504606846976bytes = 1024pebibytes

The exbibyte is closely related to the exabyte (EB), the corresponding unit in the decimal system of multiples, which is defined as 10¹⁸ bytes = 1000000000000000000bytes. It follows that one exbibyte (1 EiB) is approximately equal to 1.15 EB.
