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.
The exbibit is a multiple of the bit, a unit of digital information storage, prefixed by the standards-based multiplier exbi (symbol Ei), a binary prefix meaning 260. The unit symbol of the exbibit is Eibit. 1 exbibit = 260 bits = 1 152 921 504 606 846 976 bits = 1024 pebibits.
