How to Convert Megabyte to Mebibyte
- 1 MB = 0.9536743164 MiB
- 1 MiB = 1.048576 MB
- Example: convert 15 MB to MiB: 15 MB = 15 × 0.9536743164 MiB = 14.30511475 MiB
Formula
MiB = MB × 0.9536743164063
or MiB = MB ÷ 1.048576
Derivation from SI units:
- 1 MB = 10⁶ bytes = 8 × 10⁶ bits (decimal, SI).
- 1 MiB = 2²⁰ bytes = 1,048,576 bytes.
- 1 MB = 8000000 bit ÷ 8388608 bit per MiB = 0.9536743164063 MiB
Both units are defined exactly, so the factor is exact. Megabyte definition: megabyte; Mebibyte definition: mebibyte.
Worked examples
- A reading of 16 MB converts to 15.25878906 MiB.
16 MB × 0.9536743164 = 15.25878906 MiB - A value of 128 MB is 122.0703125 MiB.
128 MB × 0.9536743164 = 122.0703125 MiB
