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

A terabyte (TB) is a unit of digital information equal to one trillion bytes (1012 bytes).
To put that massive number into perspective, if one byte was a single printed letter, a terabyte could hold the text of over one million books.
Understanding these units is key to knowing how much data your devices can store.
A single terabyte (TB) can store an enormous amount of digital information.
For most people, 1 TB offers more than enough space for years of use. Here's what a terabyte looks like in practical terms:
This vast capacity is why external hard drives and cloud storage plans are now commonly measured in terabytes, meeting the demands of modern high-resolution media and large files.
While the terms are often used interchangeably, a terabyte and a tebibyte represent different amounts of data.
This discrepancy is why your new 1 TB hard drive shows up as approximately 931 GB in your computer.
The OS is measuring in tebibytes but often mislabels it as terabytes or gigabytes.
The first terabyte hard drive was introduced in 2007, a milestone that once seemed impossibly large.
Today, terabyte-sized drives are standard for consumer laptops, desktop computers, and gaming consoles.
As data creation continues to explode, the world is moving beyond the terabyte. The next major unit of measurement is the petabyte (PB), which is equal to 1,000 terabytes.
Large-scale data centers for companies like Google and Meta now manage data measured in exabytes—equivalent to one million terabytes.
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.
