What is a Megabit and a Bit?

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 bit (short for binary digit) is the most basic unit of information in computing and digital communications. A single bit can have only one of two values, typically represented as 0 or 1.

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

History of the Megabit and Bit

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 term "bit" was first coined by John W. Tukey in a Bell Labs memo in 1947 and popularized by Claude Shannon in his seminal 1948 paper "A Mathematical Theory of Communication". Shannon used the bit as the fundamental unit of information entropy. Early computing relied directly on manipulating bits through mechanical relays or vacuum tubes.

Common Uses for megabits and bits

Explore the typical applications for both Megabit (imperial/US) and Bit (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 bits

Representing binary states (on/off, true/false).
Quantifying information entropy.
Measuring data transfer rates (e.g., kilobits per second - kbps).
Fundamental building block for all digital data (bytes, kilobytes, etc.).
Processor architecture specifications (e.g., 32-bit, 64-bit processors).

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 Bit (b)

How many bits are in a byte?

There are typically 8 bits in 1 byte. This is the most common standard in modern computing.

What does a bit represent?

A bit represents the smallest possible unit of information, corresponding to a choice between two possibilities. In electronics, this is often represented by the presence or absence of an electrical charge or voltage level.

Why is it called a binary digit?

It's called a binary digit because it exists in a binary (base-2) system, meaning it can only have one of two possible values (0 or 1), unlike the decimal system (base-10) which uses digits 0 through 9.
