A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use.
View the gigabyte data unit pageHow to Convert Gibibytes to Gigabytes
To convert gibibytes (binary/IEC) to gigabytes (decimal/SI), multiply by 1.073741824. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales.
GiB is a binary (IEC) unit where 1 GiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations.
GB is a decimal (SI) unit where 1 GB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Related: Gibibytes to Terabytes.
1 GiB = 1.073741824 GB (using SI decimal standard) — which means there are 1.073741824gigabytes in every gibibyte.

SI Decimal vs Binary: Why Two Different Standards?
When converting gibibytes to gigabytes, 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: Gibibyte to Gigabyte Conversion
How many gigabytes are in 1 gibibyte?
1 Gibibyte (GiB) equals 1.073741824 Gigabytes using the SI decimal standard.
