What is a Megabit and a Gibibit?

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).

A gibibit (Gib) is a unit of digital information equal to 230 bits, which is exactly 1,073,741,824 bits. It uses the binary prefix 'gibi-' established by the International Electrotechnical Commission (IEC). The gibibit is closely related to the gigabit (Gb), which is defined using the decimal prefix 'giga-' (109 bits).

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

History of the Megabit and Gibibit

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 'gibi-' (representing 230) was defined by the IEC in 1998 along with other binary prefixes (kibi-, mebi-, tebi-, etc.). This standardization aimed to eliminate the confusion caused by using SI prefixes (like kilo-, mega-, giga-) to denote both powers of 1000 (decimal) and powers of 1024 (binary) in computing contexts. The term 'gibibit' specifically refers to the 230 multiple of bits.

Common Uses and Applications: megabits vs gibibits

Explore the typical applications for both Megabit (imperial/US) and Gibibit (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).

When to Use gibibits

While less common in everyday usage than the gigabit (Gb) which is often used for network speeds (Gbps), the gibibit is important where binary precision is required:

  • Specifying memory chip capacities at the bit level in technical documentation.
  • Internal calculations within networking hardware or software that operate on binary multiples.
  • Theoretical calculations in computer science, information theory, and data transmission analysis.
  • Comparing binary (Gib) and decimal (Gb) data quantities accurately.

Additional Unit Information

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 Gibibit (Gib)

How many bits are in a gibibit?

There are exactly 230 bits in 1 gibibit (Gib). This equals 1,073,741,824 bits.

How many mebibits (Mib) are in a gibibit (Gib)?

There are 1,024 mebibits (Mib) in 1 gibibit (Gib). This is because 1 Gib = 230 bits and 1 Mib = 220 bits, and 230 / 220 = 210 = 1,024.

What is the difference between a gibibit (Gib) and a gigabit (Gb)?

A gibibit (Gib) represents 230 bits (1,073,741,824 bits), using the binary prefix 'gibi-'. A gigabit (Gb) represents 109 bits (1,000,000,000 bits), using the decimal prefix 'giga-'. A gibibit is approximately 7.37% larger than a gigabit (1 Gib ≈ 1.074 Gb).

What is the difference between a gibibit (Gib) and a gibibyte (GiB)?

A gibibit (Gib) measures information in bits, while a gibibyte (GiB) measures information in bytes. Assuming the standard 1 byte = 8 bits, 1 gibibyte (GiB) is equal to 8 gibibits (Gib). Both use the binary prefix 'gibi-' (230).
