About both units

From

Megabyte

The megabyte equals 1,000,000 bytes (SI) or 1,048,576 bytes (binary, MiB). Used for photos, songs and medium-size documents. A standard MP3 song is 3–5 MB.

Real-world: MP3 song: 3–5 MB. High-res JPEG: 2–8 MB. PDF ebook: 5–50 MB.

Byte

The byte equals 8 bits — the basic unit of file size and memory. One byte encodes one ASCII character. All file sizes and RAM capacities are quoted in bytes and their multiples (KB, MB, GB, TB).

Real-world: An ASCII character: 1 byte. A short text message: few hundred bytes. Uncompressed photo: few MB.

Tips & common mistakes

Quick tips

SI: 1 MB = 1000 KB = 1,000,000 B.
Binary MiB = 1,048,576 B — 4.86% larger.
HD drives, networks, SSDs: SI MB.

Avoid these

Mixing MB and MiB without noting the difference (~5%).
Confusing MB (storage) with Mb (megabit, 1/8).
Assuming 1 GB = 1000 MB always — correct in SI; binary it's 1024.
