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 kilobit (kb or kbit) is a multiple of the bit unit for digital information or computer storage. The prefix kilo- (symbol k) is defined in the International System of Units (SI) as a multiplier of 103 (1 thousand). Therefore, 1 kilobit = 1000 bits.
Note: The Megabit is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Kilobit belongs to the imperial/US customary system.
History of the Megabit and Kilobit
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 use of the "kilo" prefix for bits emerged alongside its use for bytes as computer systems grew. While "kilobyte" was often ambiguously used for 1024 bytes (correctly kibibyte), the term "kilobit" (especially in data transmission contexts) more consistently adhered to the SI standard definition of 1000 bits. The introduction of binary prefixes like 'kibi-' (for kibibit, Kib) aimed to resolve such ambiguities.
Common Uses and Applications: megabits vs kilobits
Explore the typical applications for both Megabit (imperial/US) and Kilobit (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 kilobits
Kilobits are frequently used in specific contexts:
- Measuring data transfer rates (e.g., internet connection speeds in kbps - kilobits per second, or Mbps - megabits per second).
- Quantifying the capacity of certain types of serial communication channels.
- Specifying audio or video streaming bitrates (e.g., a 128 kbps MP3 audio file).
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 Kilobit (kb)
How many bits are in a kilobit (kb)?
There are exactly 1000 bits in 1 kilobit (kb), based on the standard SI definition of the prefix 'kilo-'.
What is the difference between a kilobit (kb) and a kilobyte (KB)?
They measure different aspects of data, though both use the 'kilo-' prefix:
- A kilobit (kb) measures bits and equals 1000 bits. It's often used for data transfer rates.
- A kilobyte (KB) measures bytes and, according to SI standards, equals 1000 bytes. It's often used for file sizes and storage capacity. (Note: Historically, KB was sometimes used informally for 1024 bytes, which is correctly termed a kibibyte (KiB)).
Since 1 byte = 8 bits, 1 kilobyte (1000 bytes) is equal to 8000 bits. Therefore, a kilobyte represents 8 times more data than a kilobit.
What is the difference between a kilobit (kb) and a kibibit (Kib)?
- A kilobit (kb) uses the decimal SI prefix 'kilo-' and equals 103 bits (1,000 bits).
- A kibibit (Kib) uses the binary IEC prefix 'kibi-' and equals 210 bits (1,024 bits).
A kibibit is 2.4% larger than a kilobit (1 Kib = 1.024 kb). Using Kib provides clarity when specifically referring to 1,024 bits, distinguishing it from the standard kilobit (1000 bits).
Why are internet speeds measured in kilobits (kbps) or megabits (Mbps)?
Data transmission over networks and communication lines often happens serially, meaning one bit is sent after another. Measuring the speed in bits per second (kbps, Mbps, Gbps) provides a direct count of how many of these individual bits can be transferred over the line in one second. Storage capacity (like hard drives or file sizes) is usually measured in bytes (KB, MB, GB) because data is typically organized and accessed in groups of 8 bits (bytes).
