Convert Kibibytes to Kilobytes (KiB to kB)
1 kibibyte (KiB) = 1.024 kilobytes (kB). 1 kB = 0.9765625 KiB. Example: 15 KiB = 15 × 1.024 = 15.36 kB.

How to Convert Kibibyte to Kilobyte
- 1 KiB = 1.024 kB
- 1 kB = 0.9765625 KiB
- Example: convert 15 KiB to kB: 15 KiB = 15 × 1.024 kB = 15.36 kB
Formula
kB = KiB × 1.024
Derivation from SI units:
- 1 KiB = 2¹⁰ bytes = 1024 bytes.
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
- 1 KiB = 8192 bit ÷ 8000 bit per kB = 1.024 kB
Both units are defined exactly, so the factor is exact. Kibibyte definition: kibibyte; Kilobyte definition: kilobyte.
Worked examples
- A reading of 16 KiB converts to 16.384 kB.
16 KiB × 1.024 = 16.384 kB - A value of 128 KiB is 131.072 kB.
128 KiB × 1.024 = 131.072 kB
