Single conversion
To convert from Gigabit (Gb) to Kibibyte (KiB), use the following formula:
With is the ratio between the base units Kibibyte (KiB) and Bit (bit).
Let's convert 5 Gigabit (Gb) to Kibibyte (KiB).
Using the formula:
Therefore, 5 Gigabit (Gb) is equal to Kibibyte (KiB).

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 kibibyte (KiB) is a unit of digital information established by the International Electrotechnical Commission (IEC).
It was created to provide a more precise way to measure data storage and eliminate common confusion with a similar-sounding unit, the kilobyte.
The core difference lies in the number system they use: binary vs. decimal.
A kibibyte (KiB) represents exactly 1,024 bytes. This number comes from the binary system (or base-2 math) that computers use, as it's a power of two (210).
In contrast, a kilobyte (KB) is often used, especially in marketing for storage devices, to mean exactly 1,000 bytes. This is based on the decimal system (or base-10 math) we use every day.
This difference is why the kibibyte was created: to offer a clear and unambiguous term for the binary-based measurements that computers and operating systems actually use.
To put it simply:
Kilobyte (KB)
Kibibyte (KiB)
Before 1998, the term "kilobyte" was ambiguously used to refer to both 1,000 and 1,024 bytes, which confused consumers and programmers alike.
To solve this problem, the IEC officially introduced a new set of prefixes specifically for binary measurements.
This new standard gave us the kibi (for kibibyte), mebi (for mebibyte, MiB), and gibi (for gibibyte, GiB), creating a transparent and standardized system for measuring data in the way computers actually "think."
Have you ever bought a 1 terabyte (TB) hard drive, only to plug it in and see your computer report it as having around 931 gigabytes (GB) of space?
You haven't been short-changed or lost any storage—it's just a difference in measurement systems.
Here's what's happening:
Ultimately, no storage is lost. It's like the difference between miles and kilometers—the distance is the same, you're just using a different unit to measure it.
