Formula
bytes = megabytes × 1000000.
Example
10 megabytes = 10000000 bytes.
What is a megabyte?
A megabyte (MB) is 1,000 kilobytes — about a minute of MP3 audio.
What is a byte?
A byte (B) is 8 bits, the basic unit of digital information (one character).
Real-world reference points
A photo is a few MB; an MP3 song ~4 MB; an HD movie ~4 GB; a modern phone stores 128+ GB.
| Reference | megabytes | bytes |
|---|---|---|
| E-mail (text only) | 0.02 MB | 20,000 B |
| Smartphone photo | 3 MB | 3,000,000 B |
| MP3 song | 4 MB | 4,000,000 B |
| DVD capacity | 4,700 MB | 4,700,000,000 B |
| HD movie stream | 4,000 MB | 4,000,000,000 B |
Mistakes to avoid with data conversions
- Megabits vs megabytes: your '100 Mbps' connection downloads at ~12.5 MB/s — ISPs quote bits, files are bytes.
- Decimal vs binary units: drives are sold in decimal GB (10⁹), so a '1 TB' drive shows ~931 'GB' (GiB) in Windows.
- Assuming video size scales with length only — resolution and bitrate matter more than minutes.
