The exbibyte (symbol EiB) is 260 bytes of digital information. It is one of a set of units with binary prefixes defined by the International Electrotechnical Commission (IEC).[1]

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

1 exbibyte = 260 bytes = 1152921504606846976bytes = 1024pebibytes

The exbibyte is approximately equal to 1.15 exabytes (EB), the corresponding unit in the decimal system of multiples, which is defined as 1018 bytes = 1000000000000000000bytes.

One exbibyte (1 EiB) is equal to eight exbibits (8 Eibit).

One thousand twenty-four exbibytes (1024 EiB) is equal to one zebibyte (1 ZiB).
