To convert from Gigabyte (GB) to Terabit (Tb), use the following formula:
With is the ratio between the base units Bit (bit) and Byte (byte).
Let's convert 5 Gigabyte (GB) to Terabit (Tb).
Using the formula:
Therefore, 5 Gigabyte (GB) is equal to Terabit (Tb).

Ever wondered what a gigabyte (GB) really means when you're buying a new phone, choosing a mobile data plan, or saving a file? A gigabyte is one of the most common measurements of digital capacity.
In this guide, we'll break down exactly what a GB is, what you can fit into it, and why the storage space you buy isn't always what you see on your device.
A gigabyte (GB) is a unit of digital data storage, equal to one billion bytes. The plural form is gigabytes.
While a gigabyte (GB) is commercially defined as 1 billion bytes (109 bytes), operating systems like Windows often measure storage using a binary system.
In this system, the correct term is a gibibyte (GiB), which is equal to 230 or 1,073,741,824 bytes.
This ~7.4% difference is why a hard drive advertised as 500 GB might appear as only 465 GiB on your computer.
This discrepancy exists because manufacturers sell storage using the decimal system (powers of 10), while most operating systems measure it using the binary system (powers of 2).
A single gigabyte (1GB) offers a substantial amount of storage for everyday use.
For perspective, 1 GB can typically hold:
This capacity makes it a standard unit for measuring file sizes, app downloads, and mobile data plans.
In the early 1980s, a gigabyte of storage was an immense, costly amount of data, primarily found in multi-million dollar supercomputers.
The first gigabyte-capacity hard disk drive, IBM's 3380, was released in 1980. It weighed over 500 pounds and cost tens of thousands of dollars.
Today, gigabytes are a routine measure for devices that fit in our pockets, such as smartphones, SD cards, and USB drives, showcasing the exponential growth of data technology.
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:
