How to Convert Mebibyte to Byte
- 1 MiB = 1048576 B
- 1 B = 9.536743164 × 10⁻⁷ MiB
- Example: convert 15 MiB to B: 15 MiB = 15 × 1048576 B = 15728640 B
Formula
B = MiB × 1048576
Derivation from SI units:
- 1 MiB = 2²⁰ bytes = 1,048,576 bytes.
- 1 byte = 8 bits (an octet).
- 1 MiB = 8388608 bit ÷ 8 bit per B = 1048576 B
Both units are defined exactly, so the factor is exact. Mebibyte definition: mebibyte; Byte definition: byte.
Worked examples
- A reading of 16 MiB converts to 16777216 B.
16 MiB × 1048576 = 16777216 B - A value of 128 MiB is 134217728 B.
128 MiB × 1048576 = 134217728 B
