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. Kibibit (Kib) is an IEC binary unit: each prefix step multiplies by 1,024, so 1 Kib = 1,024 bits. Dividing one by the other gives 7.8125, which is why KB to Kib is not a round number. Because one unit counts bits and the other bytes, the factor also includes a factor of 8.

KB and Kib: standard, prefix step and bits
Unit Standard Prefix step 1 unit equals
Kilobyte (KB) SI decimal 1,000 8,000 bits
Kibibit (Kib) Binary (IEC) 1,024 1,024 bits

To compare like with like, use KB to Kb for SI decimal or KiB to Kib for binary (IEC).

FAQs: Kilobyte to Kibibit Conversion

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

  1. How many kibibits are in 1 kilobyte?

    1 KB = 7.8125 Kib

    1 Kilobyte (KB) equals 7.8125 Kibibits using the SI decimal standard.

  2. How many kilobytes are in 1 kibibit?

    1 Kib = 0.128 KB

    1 Kibibit (Kib) equals 0.128 Kilobytes.

  3. How do I convert kilobytes to kibibits?

    KB × 7.8125 = Kib

    Multiply the kilobyte value by 7.8125 to get kibibits. For example, 10 KB = 78.125 Kib. To convert back (vice versa), multiply kibibits by 0.128.

  4. Is a kilobyte bigger than a kibibit?

    KB is 7.8125× larger than Kib

    Yes. 1 KB = 7.8125 Kib, so the kilobyte is the larger data storage unit.

  5. Why is KB to Kib not a round number?

    1 KB = 8,000 bits · 1 Kib = 1,024 bits

    Kilobyte (KB) is an SI decimal (base 10) unit and Kibibit (Kib) is a binary IEC (base 2) unit, so their prefixes step by 1,000 and 1,024. That is why 1 KB = 7.8125 Kib instead of a round number. Because one unit counts bits and the other bytes, the factor also includes a factor of 8.

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

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