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.
