Formula

Formula
kB = KiB × 1.024

Multiply any value in kibibytes by 1.024 to obtain the value in kilobytes.

Worked example

Convert 1000 KiB to kB.

  1. 01Start with 1000 KiB.
  2. 02Multiply by the conversion factor: 1000 × 1.024 = 1024 kB.
Result1000 KiB = 1024 kB

FAQ

What is the conversion factor from KiB to kB?
1 KiB equals 1.024 kB. To convert, multiply the value in kibibytes by 1.024.
How do I convert 1 KiB to kB?
1 KiB = 1.024 kB. For any value, multiply by 1.024.
How do I convert kB back to KiB?
Divide by the same factor — or equivalently, multiply by 0.9765625. So 1 kB = 0.976563 KiB.
When would I need to convert kibibyte to kilobyte?
Digital data-storage conversions between KiB and kB are routine in IT, networking, storage-array engineering, datacenter capacity planning, cloud-cost reconciliation, embedded systems and scientific data acquisition. Decimal (SI) units (kB, MB, GB, TB, PB) use base-10 multiples: 1 kB = 1,000 bytes. Binary (IEC 80000-13) units (KiB, MiB, GiB, TiB, PiB) use base-2 multiples: 1 KiB = 1,024 bytes. 1 byte = 8 bits exactly across both ladders. This category is storage size only — it does NOT cover data-transfer rate (bit/s, MB/s), download-time, bandwidth, compression-ratio assumptions or storage-pricing calculators, all of which require additional information beyond a single linear factor.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
