To convert from Megabit (Mb) to Kibibit (Kib), use the following formula:
With is the ratio between the base units Kibibit (Kib) and Bit (bit).
Let's convert 5 Megabit (Mb) to Kibibit (Kib).
Using the formula:
Therefore, 5 Megabit (Mb) is equal to Kibibit (Kib).

A megabit (Mb) is a unit of digital information, equal to one million bits (106 bits). The plural form is megabits.
While it's a fundamental unit of data, it's most commonly used to describe the speed of an internet connection.
When you shop for a broadband plan, the internet speed advertised by providers is measured in megabits per second (Mbps).
This metric defines your data transfer rate—essentially, how many million bits of data your connection can download or upload every second.
For example, a 25 Mbps download speed is great for basic browsing and streaming HD video on one device.
However, a faster plan of 100+ Mbps is better for a household with multiple people streaming 4K video, online gaming, and downloading large files at the same time.
A common point of confusion is the difference between a megabit (Mb) and a megabyte (MB).
The key is to notice the difference between the lowercase 'b' (bit) and the uppercase 'B' (byte).
Think of it this way: a bit is like a single letter, while a byte is like a complete word. Since it takes eight bits to make one byte, a megabyte (MB) is eight times larger than a megabit (Mb).
This is why they're used for different things:
In the world of networking, the "mega" prefix in megabit is simple: it means exactly 1,000,000 bits (106 bits). This is based on the decimal system.
However, you might see "mega" used differently for computer memory or file storage, where it can sometimes mean the binary equivalent of 1,048,576 bits (220 bits).
To avoid confusion, the term mebibit (Mib) was created for the binary value. Still, for measuring your internet speed, megabit (Mb) is the universal standard.
A kibibit (Kib) is a unit of digital information used to measure data capacity and transmission speeds with technical precision.
It's part of a system created by the International Electrotechnical Commission (IEC) to clear up confusion in computing.
The term "kibibit" is a combination of "kilo-binary bit."
It was created to solve the long-standing confusion between two different counting systems:
This distinction is crucial for technical accuracy in fields like software development and data storage.
While marketing for hard drives and internet speeds often uses familiar decimal prefixes (like megabit and gigabyte), technical fields rely on binary units like kibibits, mebibits, and gibibits.
For example, your computer's RAM capacity is measured in powers of two, making gibibytes (GiB) a more accurate descriptor than gigabytes (GB).
Using kibibits and other binary units eliminates ambiguity and ensures calculations for memory allocation and file sizes are precise.
It's essential to understand the size difference when comparing these units.
A single kibibit is 1,024 bits, while a kilobit is 1,000 bits.
While that 24-bit difference (about 2.4%) seems small, it becomes significant at larger scales.
This is the exact reason why your new 1 terabyte (TB) hard drive, which contains 1 trillion bytes, is reported by your operating system as only about 931 gibibytes (GiB). The manufacturer uses the decimal (base-10) definition, while your computer uses the more accurate binary (base-2) one.
