What is a Megabit and a Exabit?

A megabit (Mb or Mbit) is a multiple of the bit unit for digital information or computer storage. The prefix mega- (symbol M) is defined in the International System of Units (SI) as a multiplier of 106 (1 million). Therefore, 1 megabit = 1,000,000 bits (or 1000 kilobits).

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-'.

Note: The Megabit is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Exabit belongs to the imperial/US customary system.

History of the Megabit and Exabit

As data transfer speeds increased beyond the kilobit range, the megabit became a common unit, particularly in networking and telecommunications. Like the kilobit, it generally adheres to the SI standard (106 bits) rather than the binary interpretation sometimes used for bytes (which would be 220 bits, correctly termed a mebibit). The introduction of binary prefixes like 'mebi-' aimed to resolve this potential ambiguity.

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 for megabits and exabits

Explore the typical applications for both Megabit (imperial/US) and Exabit (imperial/US) to understand their common contexts.

Common Uses for megabits

Measuring data transfer rates (e.g., internet connection speeds in Mbps - megabits per second).
Quantifying network bandwidth.
Specifying the capacity of older storage media or certain types of memory chips.
Video and audio bitrates (e.g., streaming quality often measured in Mbps).

Common Uses for exabits

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.

Frequently Asked Questions

Questions About Megabit (Mb)

How many bits are in a megabit?

There are exactly 1,000,000 bits (or 106 bits) in 1 megabit (Mb), based on the standard SI definition of the prefix 'mega-'.

What is the difference between a megabit (Mb) and a megabyte (MB)?

A megabit (Mb) measures bits and equals 1,000,000 bits. It's often used for data transfer rates.
A megabyte (MB) measures bytes. According to SI standards, it equals 1,000,000 bytes. (Note: Historically, MB was sometimes used informally for 1,048,576 bytes, which is correctly termed a mebibyte (MiB)).

Since 1 byte = 8 bits, 1 megabyte (1,000,000 bytes) is equal to 8,000,000 bits. Therefore, a megabyte represents 8 times more data than a megabit.

What is the difference between a megabit (Mb) and a mebibit (Mib)?

A megabit (Mb) uses the decimal SI prefix 'mega-' and equals 106 bits (1,000,000 bits).
A mebibit (Mib) uses the binary IEC prefix 'mebi-' and equals 220 bits (1,048,576 bits).

A mebibit is approximately 4.86% larger than a megabit (1 Mib ≈ 1.0486 Mb). Using Mib provides clarity when specifically referring to 1,048,576 bits.

If my internet speed is 100 Mbps, how fast is that in MBps?

To convert Mbps (megabits per second) to MBps (megabytes per second), you divide by 8 (since 1 byte = 8 bits). So, 100 Mbps / 8 = 12.5 MBps. This means you can theoretically download 12.5 megabytes of data per second.

About Exabit (Eb)

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.
