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 or Eib.
The exbibit is closely related to the exabit, the corresponding unit using the metric prefix exa, which is 1018 bits = 1000000000000000000bits.
The binary prefixes are not part of the International System of Units (SI).
