Exabit (Eb) - Unit Information & Conversion
What is a Exabit?
Definition
An exabit (Eb) is a unit of digital information equal to 1018 bits, or 1,000,000,000,000,000,000 bits (one quintillion bits). It uses the standard SI decimal prefix 'exa-'.
History
The prefix 'exa-' (representing 1018) was adopted as an SI prefix by the General Conference on Weights and Measures (CGPM) in 1975. Its application to the bit (exabit) followed the increasing need to quantify extremely large amounts of digital information and data transfer rates in telecommunications and large-scale networking.
Common Uses
Exabits are used to measure very large volumes of data, typically in contexts such as:
- Total global internet traffic over extended periods (e.g., annually).
- Aggregate data transfer across major international network backbones.
- Theoretical capacities of future large-scale data storage systems or networks.
- High-level discussions of data generated by large scientific projects (like particle physics or astronomy).
It is less common in consumer contexts compared to smaller units like gigabits or terabits.
Unit FAQs
How many bits are in an exabit?
There are 1018 (one quintillion, or 1 followed by 18 zeros) bits in 1 exabit (Eb).
How many petabits (Pb) are in an exabit (Eb)?
There are 1,000 petabits (Pb) in 1 exabit (Eb), since 'peta-' represents 1015 and 'exa-' represents 1018.
What is the difference between an exabit (Eb) and an exabyte (EB)?
An exabit (Eb) measures data in bits, while an exabyte (EB) measures data in bytes. Since 1 byte typically equals 8 bits, 1 exabyte (EB) is equal to 8 exabits (Eb).
What is the difference between an exabit (Eb) and an exbibit (Eib)?
An exabit (Eb) uses the decimal prefix 'exa-' (1018 bits). An exbibit (Eib) uses the binary prefix 'exbi-' (260 bits). An exbibit is significantly larger than an exabit (approximately 1.15 Eb). Exbibits are used when specifically referring to powers-of-2 multiples in computing contexts.
