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.
