View the kilobyte data unit pageHow to Convert Kibibytes to Kilobytes
To convert kibibytes (binary/IEC) to kilobytes (decimal/SI), multiply by 1.024. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales.
KiB is a binary (IEC) unit where 1 KiB = 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: Kibibytes to Megabytes.
1 KiB = 1.024 KB (using SI decimal standard) — which means there are 1.024kilobytes in every kibibyte.
KiB to KB conversion rate: 1 kibibyte equals 1.024kilobytes — the standard kibibyte to kilobyte data storage conversion used by this calculator.

SI Decimal vs Binary: Why KiB 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. Kibibyte (KiB) is an IEC binary unit: each prefix step multiplies by 1,024, so 1 KiB = 8,192 bits. Dividing one by the other gives 1.024, which is why KiB to KB is not a round number.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Kibibyte (KiB) | Binary (IEC) | 1,024 | 8,192 bits |
| Kilobyte (KB) | SI decimal | 1,000 | 8,000 bits |

1 KiB = 1.024 KB
1 Kibibyte (KiB) equals 1.024 Kilobytes using the SI decimal standard.
-
How many kibibytes are in 1 kilobyte?
1 KB = 0.9765625 KiB
1 Kilobyte (KB) equals 0.9765625 Kibibytes.
-
How do I convert kibibytes to kilobytes?
KiB × 1.024 = KB
Multiply the kibibyte value by 1.024 to get kilobytes. For example, 10 KiB = 10.24 KB. To convert back (vice versa), multiply kilobytes by 0.9765625.
-
Is a kibibyte bigger than a kilobyte?
KiB is 1.024× larger than KB
Yes. 1 KiB = 1.024 KB, so the kibibyte is the larger data storage unit.
-
Why is KiB to KB not a round number?
1 KB = 8,000 bits · 1 KiB = 8,192 bits
Kilobyte (KB) is an SI decimal (base 10) unit and Kibibyte (KiB) is a binary IEC (base 2) unit, so their prefixes step by 1,000 and 1,024. That is why 1 KiB = 1.024 KB instead of a round number.
-
What is Kibibyte (KiB) commonly used for?
Common uses of the kibibyte (KiB) include: RAM specifications, operating system file sizes, memory allocation.
