Because Exabits are ambiguous and misuse the prefix "exa" as defined by the International System of Units, the International Electrotechnical Commission established exbibits in 1998.
An Exbibit is always equal to 2^60, or 1,152,921,504,606,846,976 bits or 1024 pebibits.
As a unit of measurement, Exbibits have no practical uses as of today.
Exbibits are 1,024 pebibits and precede zebi and yobi in bit measurement.
Very similar to exabits, which use a less exact prefix established by the International System of Units (SI) but are used much more commonly.
