About these units

Short background on the units used in this conversion.

Kilobyte (KB)

A decimal kilobyte (KB) is exactly 1,000 bytes — the SI-style prefix used by storage vendors and many operating systems.

Decimal KB and MB appear on USB drive labels, broadband speed marketing, and macOS storage displays.

Megabyte (MB)

A decimal megabyte (MB) is exactly 1,000,000 bytes (1,000 KB) — not to be confused with the binary mebibyte (MiB).

Decimal MB sizes photo attachments, app downloads, and cloud storage tiers on many consumer devices.
