To convert from Gibibyte (GiB) to Terabyte (TB), use the following formula:
With is the ratio between the base units Byte (byte) and Kibibyte (KiB).
Let's convert 5 Gibibyte (GiB) to Terabyte (TB).
Using the formula:
Therefore, 5 Gibibyte (GiB) is equal to Terabyte (TB).

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
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.
