Convert Mebibytes to Kilobytes (MiB to kB)
1 mebibyte (MiB) = 1048.576 kilobytes (kB). 1 kB = 0.0009536743164 MiB. Example: 15 MiB = 15 × 1048.576 = 15728.64 kB.

How to Convert Mebibyte to Kilobyte
- 1 MiB = 1048.576 kB
- 1 kB = 0.0009536743164 MiB
- Example: convert 15 MiB to kB: 15 MiB = 15 × 1048.576 kB = 15728.64 kB
Formula
kB = MiB × 1048.576
Derivation from SI units:
- 1 MiB = 2²⁰ bytes = 1,048,576 bytes.
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
- 1 MiB = 8388608 bit ÷ 8000 bit per kB = 1048.576 kB
Both units are defined exactly, so the factor is exact. Mebibyte definition: mebibyte; Kilobyte definition: kilobyte.
Worked examples
- A reading of 16 MiB converts to 16777.216 kB.
16 MiB × 1048.576 = 16777.216 kB - A value of 128 MiB is 134217.728 kB.
128 MiB × 1048.576 = 134217.728 kB
