How to convert gibibytes to gigabytes
To convert a measurement in gibibytes to gigabytes, multiply the value by 1.073742. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 GiB to gigabytes: 5 × 1.073742 = 5.368709 GB.
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 gigabyte?
A gigabyte is 1,000,000,000 bytes (1,000 megabytes) under the SI decimal convention. The binary equivalent of 1,073,741,824 bytes is the gibibyte (GiB). The gigabyte became the standard consumer storage unit with the rise of hard drives, USB sticks, and smartphones. Drive makers market capacity in decimal gigabytes, while operating systems often report in binary gibibytes, which is why a '500 GB' drive shows as about 465 GB.
Common uses of gigabytes include: Hard drive, SSD, and USB flash storage capacity; Smartphone and tablet storage tiers; HD video and large software installs; RAM and memory-card sizing.

Frequently asked questions
How many gigabytes are in one gibibyte?
One gibibyte (GiB) equals 1.073742 gigabytes (GB). Multiply any value in gibibytes by 1.073742 to convert to gigabytes.
How do I convert gibibytes to gigabytes?
Multiply the value in gibibytes by 1.073742. For example, 5 GiB × 1.073742 = 5.368709 GB.
How do I convert gigabytes to gibibytes?
Multiply the value in gigabytes by 0.931322574615, or divide by 1.073742. Use the swap button on the converter above to reverse the direction.
Is the gibibyte to gigabyte 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 gigabytes?
The formula is: GB = GiB × 1.073742. This comes from the definition of both units relative to the byte.
