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

A Gigabit (Gb) is a unit of digital information equal to one billion bits (109 bits).
It's a key measurement used to describe the speed of data transfer, most commonly your internet connection speed.
It's easy to mix up a Gigabit (Gb) and a Gigabyte (GB), but they measure two very different things: speed vs. size.
The most important thing to remember is this simple conversion:
This is why a fast 1 Gbps internet connection doesn't download a 1 GB file in one second.
Since a Gigabyte is eight times larger than a Gigabit, it will take about eight seconds to complete the download.
What does a fast internet connection of 1 Gigabit per second (Gbps) mean for your daily use?
It provides the bandwidth needed to power a fully connected home or business, allowing you to:
A gigabit connection is the gold standard for reliable, high-speed internet for modern work, entertainment, and communication.
The prefix "Giga-" comes from the Greek word for "giant," and it represents a massive amount of data.
A single Gigabit is made up of one billion individual bits (the most minor units of digital data, represented by a 1 or a 0).
To put that in perspective, one Gigabit of information is enough to store the text of roughly 1,000 novels.
When you hear about Gigabit speeds, you're talking about the power to move that entire library of information every single second.
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.
