What is a Megabit and a Terabyte?

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 terabyte (TB) is a multiple of the byte unit for digital information 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 terabyte = 1,000,000,000,000 bytes. This is equivalent to 1,000 gigabytes (GB).

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

History of the Megabit and Terabyte

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 storage capacities reached trillions of bytes. Historically, the term 'terabyte' was often used ambiguously to refer to either 1012 bytes (the strict SI definition) or 240 bytes (1,099,511,627,776 bytes), which is the power of 2 closest to a trillion. This ambiguity, particularly noticeable in how operating systems reported disk sizes versus how manufacturers advertised them, led the International Electrotechnical Commission (IEC) to introduce the distinct binary prefix 'tebi-' (Ti) for 240. Thus, tebibyte (TiB) specifically denotes 240 bytes, while terabyte (TB) formally refers to 1012 bytes.

Common Uses for megabits and terabytes

Explore the typical applications for both Megabit (imperial/US) and Terabyte (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 terabytes

Terabytes are widely used to measure large amounts of digital data storage capacity:

  • Specifying the capacity of consumer and enterprise hard disk drives (HDDs) and solid-state drives (SSDs).
  • Measuring the size of large files, databases, archives, and backups.
  • Quantifying the storage space available in cloud storage plans and data centers.
  • Describing the amount of data transferred over networks or used in monthly internet data caps.
  • Indicating the capacity of personal computers, laptops, external drives, and network-attached storage (NAS) devices.

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 Terabyte (TB)

How many bytes are in a terabyte (TB)?

According to the standard SI definition, there are exactly 1,000,000,000,000 bytes (one trillion bytes, or 1012 bytes) in 1 terabyte (TB).

How many gigabytes (GB) are in a terabyte (TB)?

There are 1,000 gigabytes (GB) in 1 terabyte (TB). This follows the SI prefixes: 1 TB = 1012 bytes and 1 GB = 109 bytes. Therefore, 1 TB / 1 GB = 1012 / 109 = 103 = 1,000.

What is the difference between a terabyte (TB) and a tebibyte (TiB)?

  • A terabyte (TB) uses the decimal SI prefix 'tera-' and equals 1012 bytes (1,000,000,000,000 bytes). It's commonly used in storage device marketing.
  • A tebibyte (TiB) uses the binary IEC prefix 'tebi-' and equals 240 bytes (1,099,511,627,776 bytes). It's often used by operating systems to report storage capacity based on powers of 2. A tebibyte (TiB) is approximately 9.95% larger than a terabyte (TB) (1 TiB ≈ 1.0995 TB).

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

  • A terabyte (TB) measures data storage capacity in bytes and equals 1012 bytes.
  • A terabit (Tb) measures data quantity or data transfer speed in bits and equals 1012 bits. Assuming the standard definition of 1 byte = 8 bits, 1 terabyte (TB) is equal to 8 terabits (Tb). Calculation: 1 TB = 1012 bytes = 1012 * 8 bits = 8 * 1012 bits = 8 Tb. Therefore, a terabyte represents 8 times more data storage capacity than the equivalent number of terabits.

Why is TB often used in marketing instead of TiB?

Storage manufacturers typically market drive capacities using the decimal prefix terabyte (TB) because 1012 bytes yields a larger, rounder number compared to the equivalent value expressed using the binary prefix tebibyte (TiB) (which is 240 bytes). For instance, a hard drive containing exactly 1,000,000,000,000 bytes is advertised as 1 TB. If measured in tebibytes, this same physical capacity would be approximately 0.909 TiB (since 1012 / 240 ≈ 0.909). Using TB allows manufacturers to present higher capacity figures, which is advantageous for marketing, even though operating systems might report the capacity using the smaller TiB value.
