The megabyte
The megabyte (MB) equals 1,000,000 bytes (decimal) or 1,048,576 bytes (binary, formally 'mebibyte' MiB — a roughly 5% difference). Used for music files, photographs, and most everyday document sizes.

Real-world reference
A typical 3-minute MP3 is around 3–7 MB. A high-resolution JPEG photo is 2–8 MB. In bits, that gives you: 1 MB = 8000000 bit, 10 MB = 80000000 bit, 100 MB = 800000000 bit.
Frequently asked questions
- How many bits are in 1 megabyte?
- 1 megabyte equals 8000000 bits.
- How do I convert megabytes to bits?
- Multiply the megabyte value by 8000000. So x MB × 8000000 = the equivalent in bit.
- What is 5 megabytes in bits?
- 5 megabytes equals 40000000 bits.

- 100 megabytes equals 800000000 bits.
- How do I convert back from bits to megabytes?
- Multiply the bit value by 1.2500 × 10^−7. For example, 1 bit = 1.2500 × 10^−7 MB.
- Is the megabyte bigger than the bit?
- Yes. 1 megabyte is larger than 1 bit — specifically 8000000 times larger.
- Are these conversion factors exact?
- Yes. The factor of 8000000 is derived directly from the SI definitions of megabyte and bit.
About the megabyte and the bit
The bit
A bit is the smallest unit of digital information — a single 0 or 1. Eight bits make one byte. The bit is the natural unit for bandwidth (most network speeds are quoted in bits per second, not bytes).
