The yobibit is a multiple of the bit, a unit of digital information storage, prefixed by the standards-based multiplier yobi (symbol Yi), a binary prefix meaning 280. The unit symbol of the yobibit is Yibit. 1 yobibit = 280 bits = 1 208 925 819 614 629 174 706 176 bits = 1024 zebibits
The petabit is a multiple of the unit bit for digital information or computer storage. The prefix peta (symbol P) is defined in the International System of Units (SI) as a multiplier of 1015 (1 quadrillion, short scale), and therefore 1 petabit = 1015 bits = 1 000 000 000 000 000 bits = 1000 terabits. The petabit has the unit symbol Pbit or Pb.
