View the kilobyte data unit pageHow to Convert Gibibytes to Kilobytes
To convert gibibytes (binary/IEC) to kilobytes (decimal/SI), multiply by 1,073,742. 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.
KB is a decimal (SI) unit where 1 KB = 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 Nibbles.
1 GiB = 1,073,742 KB (using SI decimal standard) — which means there are 1,073,742kilobytes in every gibibyte.
GiB to KB conversion rate: 1 gibibyte equals 1,073,742kilobytes — the standard gibibyte to kilobyte data storage conversion used by this calculator.

SI Decimal vs Binary: Why Two Different Standards?
When converting gibibytes to kilobytes, 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 Kilobyte Conversion
How many kilobytes are in 1 gibibyte?
1 Gibibyte (GiB) equals 1,073,742 Kilobytes using the SI decimal standard.
How do I convert gibibytes to kilobytes?
Multiply the gibibyte value by 1,073,742 to get kilobytes. For example, 10 GiB = 10,737,418 KB.
Is a gibibyte bigger than a kilobyte?
Yes. 1 GiB = 1,073,742 KB, so the gibibyte is the larger data storage unit.
