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

A tebibyte (TiB) is a standard unit of digital information used in computing.
It is defined by the International Electrotechnical Commission (IEC) as exactly 240 or 1,099,511,627,776 bytes. The plural form is tebibytes.
While they sound similar, a tebibyte (TiB) is not the same as a terabyte (TB).
The key difference lies in how they are calculated.
A tebibyte is based on the binary system (powers of 2), which is the language computers use.
In contrast, a terabyte is based on the familiar decimal system (powers of 10), which is often used in marketing.
This difference in calculation means a tebibyte is nearly 10% larger than a terabyte.
This is the exact reason why your new 1 TB hard drive shows up as having only about 931 GB of usable space on your computer—your operating system is measuring in the more precise binary units (like gibibytes), while the packaging was labeled using decimal units (terabytes).
Here's a simple breakdown of the differences:
The term "tebibyte" was officially introduced by the IEC in 1998 to clear up confusion. For years, "terabyte" was ambiguously used to mean both 1012 bytes and 240 bytes.
By creating binary prefixes like "tebi" (which stands for terabinary), the IEC established a clear and unambiguous standard.
This precision is essential for software developers, computer scientists, and anyone in a technical field where exact measurements are critical.
While you'll almost always see terabytes (TB) on the packaging for hard drives (HDDs) and solid-state drives (SSDs), tebibytes (TiB) are the standard in many technical environments.
You will commonly find TiB and its smaller counterparts (like GiB) used in:
Using TiB in these fields ensures that calculations are accurate and prevents errors that can arise from confusing the two systems.
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.
