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.
