Definition of exabit [Eb] unit

An exabit (Eb) is a decimal unit of digital information equal to 1018 bits, or 1,000,000,000,000,000,000 bits. It measures extremely large data volumes and should not be confused with the binary exbibit (Eib).

History of exabit [Eb] unit

The exabit follows the International System of Units (SI) decimal prefix “exa-,” which was officially adopted in 1975 to represent a factor of 1018. As digital networks, storage systems, and scientific instruments expanded, larger information units became necessary beyond terabits and petabits. The term gained practical relevance during the growth of global internet traffic, cloud computing, high-performance research, and telecommunications. In modern usage, an exabit generally means 1018 bits; the corresponding binary quantity, 260 bits, is formally called an exbibit.

Applications of exabit [Eb] unit

Today, exabits are used mainly to describe data moving through major telecommunications networks, internet backbones, and large-scale cloud infrastructures. Analysts may report worldwide traffic, annual data generation, or aggregate transfer capacity in exabits. For example, a forecast can estimate several exabits of information crossing global networks, while researchers use the unit when discussing enormous scientific datasets.
