View the gibibyte data unit pageHow to Convert Gigabytes to Gibibytes
To convert gigabytes (decimal/SI) to gibibytes (binary/IEC), multiply by 0.931322574615. Decimal units use base 1,000, while binary units use base 1,024.
GB is a decimal (SI) unit—what storage manufacturers advertise. 1 GB = 1,000 of the smaller unit.
GiB is a binary (IEC) unit—what operating systems often display. 1 GiB = 1,024 of the smaller unit.
1 GB = 0.931322574615 GiB (using SI decimal standard) — or equivalently, 1 GiB = 1.073741824GB.

SI Decimal vs Binary: Why Two Different Standards?
When converting gigabytes to gibibytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard above the converter.
FAQs: Gigabyte to Gibibyte Conversion
How many gibibytes are in 1 gigabyte?
1 Gigabyte (GB) equals 0.931322574615 Gibibytes using the SI decimal standard.
How do I convert gigabytes to gibibytes?
Multiply the gigabyte value by 0.931322574615 to get gibibytes. For example, 10 GB = 9.3132257462 GiB.
