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

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 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.
