The yottabit is a multiple of the unit bit for digital information or computer storage. The prefix yotta (symbol Y) is defined in the International System of Units (SI) as a multiplier of 1024 (1 septillion, short scale), and therefore 1 yottabit = 1024 bits = 1 000 000 000 000 000 000 000 000 bits = 1000 zettabits. The yottabit has the unit symbol Ybit or Yb.
The yobibyte 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 YiB. The prefix yobi (symbol Yi) represents multiplication by 10248, therefore: 1 yobibyte = 280 bytes = 1 208 925 819 614 629 174 706 176 bytes = 1024 zebibytes.
