SI Decimal vs Binary: Why KB to KiB 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 0.9765625, which is why KB to KiB is not a round number.

FAQs: Kilobyte to Kibibyte Conversion

6 questions Quick answers on converting kilobytes to kibibytes, using the same factors as the converter above.

  1. How many kibibytes are in 1 kilobyte?

    1 KB = 0.9765625 KiB

    1 Kilobyte (KB) equals 0.9765625 Kibibytes using the SI decimal standard.

  2. How many kilobytes are in 1 kibibyte?

    1 KiB = 1.024 KB

    1 Kibibyte (KiB) equals 1.024 Kilobytes.

  3. How do I convert kilobytes to kibibytes?

    KB × 0.9765625 = KiB

    Multiply the kilobyte value by 0.9765625 to get kibibytes. For example, 10 KB = 9.765625 KiB. To convert back (vice versa), multiply kibibytes by 1.024.

  4. Is a kilobyte bigger than a kibibyte?

    KiB is 1.024× larger than KB

    No. 1 KB = 0.9765625 KiB, so the kibibyte is larger — 1 KiB = 1.024 KB.

  5. Why is KB to KiB 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 KB = 0.9765625 KiB instead of a round number.

  6. What is Kilobyte (KB) commonly used for?

    Common uses of the kilobyte (KB) include: Text documents, small images, email attachments, configuration files.
