Orders of magnitude of data

The zebibyte 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 ZiB.

The prefix zebi (symbol Zi) represents multiplication by 1024⁷, therefore:

1 zebibyte = 2⁷⁰ bytes = 1180591620717411303424bytes = 1024 exbibytes

The prefix zebi was originally not part of the system of binary prefixes, but was added together with the prefix yobi by the IEC in August 2005.

Usage examples

• GUID Partition Table (GPT) allows for a maximum disk and partition size of 8 zebibytes, or 9.4 zettabytes, when using 512-byte sectors.
