How to convert gibibytes to bytes
To convert a measurement in gibibytes to bytes, multiply the value by 1,073,741,824. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 GiB to bytes: 5 × 1,073,741,824 = 5,368,709,120 B.
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 byte?
A byte is a unit of digital information consisting of 8 bits. It is the standard addressable unit of memory and can represent a single text character. The byte was defined by Werner Buchholz in 1956 during the design of the IBM Stretch computer. Eight bits became the de facto standard, enough to encode a character in early text encodings like ASCII.
Common uses of bytes include: File sizes and memory addressing; Text character storage (1 byte per ASCII character); Low-level programming and data structures; Baseline unit for all larger storage measures.

Frequently asked questions
How many bytes are in one gibibyte?
One gibibyte (GiB) equals 1,073,741,824 bytes (B). Multiply any value in gibibytes by 1,073,741,824 to convert to bytes.
How do I convert gibibytes to bytes?
Multiply the value in gibibytes by 1,073,741,824. For example, 5 GiB × 1,073,741,824 = 5,368,709,120 B.
How do I convert bytes to gibibytes?
Multiply the value in bytes by 9.313226e-10, or divide by 1,073,741,824. Use the swap button on the converter above to reverse the direction.
Is the gibibyte to byte 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 bytes?
The formula is: B = GiB × 1,073,741,824. This comes from the definition of both units relative to the byte.
