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.

SI Decimal vs Binary: Why GiB to KB Is Not a Round Number
Kilobyte (KB) is an SI decimal unit: each prefix step multiplies by 1,000, so 1 KB = 8,000 bits. Gibibyte (GiB) is an IEC binary unit: each prefix step multiplies by 1,024, so 1 GiB = 8,589,934,592 bits. Dividing one by the other gives 1,073,742, which is why GiB to KB is not a round number.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Gibibyte (GiB) | Binary (IEC) | 1,024 | 8,589,934,592 bits |
| Kilobyte (KB) | SI decimal | 1,000 | 8,000 bits |
To compare like with like, use GB to KB for SI decimal or GiB to KiB for binary (IEC).
FAQs: Gibibyte to Kilobyte Conversion
6 questions Quick answers on converting gibibytes to kilobytes, using the same factors as the converter above.
-
How many kilobytes are in 1 gibibyte?
1 GiB = 1,073,742 KB
1 Gibibyte (GiB) equals 1,073,742 Kilobytes using the SI decimal standard.
-
How many gibibytes are in 1 kilobyte?
1 KB = 0.000000931322575 GiB
1 Kilobyte (KB) equals 0.000000931322575 Gibibytes.
-
How do I convert gibibytes to kilobytes?
GiB × 1,073,742 = KB
Multiply the gibibyte value by 1,073,742 to get kilobytes. For example, 10 GiB = 10,737,418 KB. To convert back (vice versa), multiply kilobytes by 0.000000931322575.
-
Is a gibibyte bigger than a kilobyte?
GiB is 1,073,742× larger than KB
Yes. 1 GiB = 1,073,742 KB, so the gibibyte is the larger data storage unit.
-
Why is GiB to KB not a round number?
1 KB = 8,000 bits · 1 GiB = 8,589,934,592 bits
Kilobyte (KB) is an SI decimal (base 10) unit and Gibibyte (GiB) is a binary IEC (base 2) unit, so their prefixes step by 1,000 and 1,024. That is why 1 GiB = 1,073,742 KB instead of a round number.
-
What is Gibibyte (GiB) commonly used for?
Common uses of the gibibyte (GiB) include: Windows/macOS file sizes, SSD actual capacity, RAM modules.
