The exabit is a multiple of the unit bit for digital information or computer storage. The prefix exa (symbol E) is defined in the International System of Units (SI) as a multiplier of 10¹⁸ (1 quintillion, short scale), and therefore

1 exabit = = = 1000 petabits.

The exabit has the unit symbol Ebit or Eb.

The exabit is closely related to the exbibit, a unit multiple derived from the binary prefix exbi of the same order of magnitude, which is equal to = , or approximately 15% larger than the exabit.
