What is a Megabit and a Terabit?

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 terabit (Tb or Tbit) is a multiple of the bit unit for digital information or computer storage. The prefix tera- (symbol T) is defined in the International System of Units (SI) as a multiplier of 1012 (1 trillion, or 1 followed by 12 zeros). Therefore, 1 terabit = 1,000,000,000,000 bits. This is equivalent to 1,000 gigabits (Gb).

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

History of the Megabit and Terabit

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 SI prefix 'tera-' (meaning 1012) was adopted for use in computing as data scales grew into the trillions of bits. Initially, 'tera-' was sometimes used ambiguously to refer to either 1012 or the nearest power of 2 (240). This ambiguity led the International Electrotechnical Commission (IEC) to introduce the binary prefix 'tebi-' (Ti) specifically for 240, clarifying that terabit (Tb) strictly refers to 1012 bits.

Common Uses for megabits and terabits

Explore the typical applications for both Megabit (imperial/US) and Terabit (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 terabits

Terabits are commonly used in contexts involving high-capacity data transmission and large-scale data measurement:

  • Measuring the data transfer rates of high-speed networks, internet backbones, and data center interconnects (often expressed in Tbps - terabits per second).
  • Quantifying the throughput of network equipment like routers and switches.
  • Describing the capacity of optical fiber communication systems.
  • Sometimes used alongside terabytes (TB) in marketing large storage devices, although TB (bytes) is more common for capacity.
  • Discussing large datasets in scientific computing and big data analytics, particularly concerning transmission speeds.

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 Terabit (Tb)

How many bits are in a terabit?

There are exactly 1,000,000,000,000 bits (one trillion bits, or 1012 bits) in 1 terabit (Tb), according to the standard SI definition of the prefix 'tera-'.

What is the difference between a terabit (Tb) and a terabyte (TB)?

  • A terabit (Tb) measures data in bits and equals 1012 bits. It is commonly used for data transfer rates.
  • A terabyte (TB) measures data in bytes. According to SI standards, it equals 1012 bytes. It is typically used for measuring storage capacity. (Note: The term tebibyte (TiB) correctly refers to 240 bytes).

Since 1 byte = 8 bits, 1 terabyte (1012 bytes) is equal to 8 x 1012 bits, or 8 terabits. Therefore, a terabyte represents 8 times more data than a terabit.

What is the difference between a terabit (Tb) and a tebibit (Tib)?

  • A terabit (Tb) uses the decimal SI prefix 'tera-' and equals 1012 bits (1,000,000,000,000 bits).
  • A tebibit (Tib) uses the binary IEC prefix 'tebi-' and equals 240 bits (1,099,511,627,776 bits).

A tebibit is approximately 9.95% larger than a terabit (1 Tib ≈ 1.0995 Tb). Use Tb for contexts adhering to decimal standards (like network speeds) and Tib when precise binary multiples (powers of 2) are required (often related to memory or specific storage architectures).

How many gigabits (Gb) are in a terabit (Tb)?

There are 1,000 gigabits (Gb) in 1 terabit (Tb). This is derived from the SI prefixes: 1 Tb = 1012 bits and 1 Gb = 109 bits. Therefore, 1 Tb / 1 Gb = 1012 / 109 = 103 = 1,000.
