Because Zettabits are ambiguous and misuse the prefix "zetta" as defined by the International System of Units, the International Electrotechnical Commission established Zebibits in 1998.

A Zebibit is always equal to 2^70, or 1,180,591,620,717,411,303,424 bits or 1024 exbibits.

As a unit of measurement, Zebibits have no practical uses as of today.

Zebibits are 1,024 exbibits and precede yobi in bit measurement.

Very similar to zettabits, which use a less exact prefix established by the International System of Units (SI) but are used much more commonly.
