How to convert gibibytes to kibibytes
To convert a measurement in gibibytes to kibibytes, multiply the value by 1,048,576. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 GiB to kibibytes: 5 × 1,048,576 = 5,242,880 KiB.
What is a gibibyte?
A gibibyte is exactly 1,073,741,824 bytes (2^30), the binary counterpart of the gigabyte defined by the IEC. This is why a 1 GB figure and a 1 GiB figure differ by about 7%. The gibibyte resolves the most visible storage confusion: drive makers sell in decimal gigabytes while operating systems report in binary gibibytes, so a '500 GB' drive is about 465 GiB of usable, OS-reported space.
Common uses of gibibytes include: Operating-system storage and RAM reporting; Virtual-machine and disk-image sizing; Reconciling advertised vs. reported drive capacity; Exact power-of-two capacity in software.
What is a kibibyte?
A kibibyte is exactly 1,024 bytes (2^10), the binary counterpart of the kilobyte defined by the IEC. Use it when you mean the power-of-two value. The IEC introduced the binary prefixes (kibi, mebi, gibi, ...) in 1998 to end the long-standing confusion between the decimal kilobyte (1,000 B) and the binary 1,024-byte unit that computing had informally called a kilobyte.
Common uses of kibibytes include: Memory and buffer sizes in software; Operating-system file-size reporting; Low-level programming and disk blocks; Any context needing an exact power-of-two size.

Frequently asked questions
How many kibibytes are in one gibibyte?
One gibibyte (GiB) equals 1,048,576 kibibytes (KiB). Multiply any value in gibibytes by 1,048,576 to convert to kibibytes.
How do I convert gibibytes to kibibytes?
Multiply the value in gibibytes by 1,048,576. For example, 5 GiB × 1,048,576 = 5,242,880 KiB.
How do I convert kibibytes to gibibytes?
Multiply the value in kibibytes by 0.000000953674, or divide by 1,048,576. Use the swap button on the converter above to reverse the direction.
Is the gibibyte to kibibyte conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for gibibytes to kibibytes?
The formula is: KiB = GiB × 1,048,576. This comes from the definition of both units relative to the byte.
