To convert from Terabit (Tb) to Gibibyte (GiB), use the following formula:
With is the ratio between the base units Kibibyte (KiB) and Bit (bit).
Let's convert 5 Terabit (Tb) to Gibibyte (GiB).
Using the formula:
Therefore, 5 Terabit (Tb) is equal to Gibibyte (GiB).

A Terabit (Tb) is a unit of digital information equal to one trillion bits (or 1012 bits). The plural form is Terabits.
While their names are similar, a terabit (Tb) and a terabyte (TB) measure different things.
A terabit is used to measure data transfer speeds, like your internet connection speed (e.g., terabits per second or Tbps).
In contrast, a terabyte measures data storage capacity, such as the size of a hard drive or a file.
Think of it like this: a terabyte (TB) is the size of a water tank (storage), while a terabit per second (Tbps) is how fast water flows through the pipe (speed).
The key relationship is that 1 terabyte (TB) is equal to 8 terabits (Tb), because there are 8 bits in every byte.
A data transfer speed of one terabit per second (Tbps) is incredibly fast—almost too quick to comprehend.
To put it in perspective, a 1 Tbps connection could theoretically download over 400 high-definition movies in a single second.
While this immense bandwidth is far beyond what any single home needs, it's essential for the infrastructure that powers our digital world.
You won't find terabit speeds advertised for home internet plans. Instead, this technology forms the backbone of the global internet.
Terabit speeds are primarily used in:
A gibibyte (GiB) is a unit of measurement for digital data.
While it sounds complex, understanding it is the key to solving a common tech mystery: why the storage space on your new device or hard drive often looks smaller than what was advertised on the box.
Have you ever purchased a 500 gigabyte (GB) hard drive, only to find that your computer reports it as having only 465 GB of storage capacity?
You haven't been short-changed. The difference comes down to two different ways of counting:
Gigabyte (GB): This is the unit manufacturers use for marketing. It's a simple, round number based on the decimal (base-10) system.
Gibibyte (GiB): This is the unit your computer's operating system (like Windows or macOS) often uses for measurement. It is based on the binary (base-2) system, which is the native language of computers.
This means a gibibyte is about 7.4% larger than a gigabyte.
So, your 500 GB hard drive has exactly 500,000,000,000 bytes, but when your computer measures those bytes using the binary system, it calculates it as approximately 465 GiB.
The amount of storage is the same—only the unit of measurement has changed.
To clear up this exact confusion, the International Electrotechnical Commission (IEC) officially introduced the term "gibibyte" in 1998.
It was created along with other binary-based prefixes (like kibi-, mebi-, and tebi-) to create a clear standard and separate the binary measurements used in computing from the decimal measurements used in marketing and general communication.
Knowing where to expect each term can help you avoid confusion:
You will see Gigabytes (GB) used most often in marketing and sales, such as on the packaging for hard drives, SSDs, smartphones, and when describing mobile data plans.
You will encounter Gibibytes (GiB) inside software environments. Operating systems, file size information, and memory (RAM) specifications use GiB to give a more precise measurement that aligns with the computer's binary architecture.
In short, the next time you see a difference in your storage numbers, you'll know it's not a mistake—it's just the language of computers at work
