The petabyte is a multiple of the unit byte for digital information. The prefix peta indicates the fifth power of 1000 and means 1015 in the International System of Units (SI), and therefore 1 petabyte is one quadrillion (short scale) bytes, or 1 billiard (long scale) bytes or 1000 terabyte, or 1 000 000 gigabytes . The unit symbol for the petabyte is PB.

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.
