Convert Bits to Mebibytes - Data Storage Converter
This converter translates bits (b) into mebibytes (MiB), the binary unit equal to 1,048,576 bytes (2^20). Use it for software, file systems, memory sizing, and any context requiring binary-accurate units.

Methodology
Core identity: 1 byte = 8 bits. Binary prefix: 1 MiB = 1,048,576 bytes (2^20).
Conversion path: bits → bytes (÷8) → MiB (÷1,048,576). Combined: MiB = bits ÷ (8 × 1,048,576).
If you need decimal megabytes (MB) instead, use the decimal factor 1 MB = 1,000,000 bytes. The bit-to-byte step remains ÷8; only the divisor changes.
Worked examples
16,777,216 bits → 2 MiB.
104,857,600 bits → 104,857,600 ÷ (8 × 1,048,576) ≈ 12.5 MiB.
1,000,000 bits → 1,000,000 ÷ (8 × 1,048,576) ≈ 0.119 MiB.
Key takeaways
MiB = bits ÷ (8 × 1,048,576). Use this for binary-accurate conversions; swap the divisor to 1,000,000 for decimal MB.
Expert Q&A
When should I use MiB instead of MB?
Use MiB for binary-accurate contexts (file systems, OS reporting, memory). Use MB for decimal contexts (vendor marketing, SI-based specs). Always match the unit convention of your audience.
Is the bit-to-byte factor different in binary?
No. 1 byte = 8 bits everywhere. The difference between MiB and MB comes from the prefix (2^20 vs 10^6), not from the bit-to-byte relationship.
How should I round?
Keep full precision for calculations. Round display values to the number of decimals required by your report or SLA (often 2–4 decimals).
