The pebibyte 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).[1] Its unit symbol is PiB.
The prefix pebi (symbol Pi) represents multiplication by 10245, therefore: 1 pebibyte = 250 bytes = 1 125 899 906 842 624 bytes = 1024 tebibytes.
