Choose the right standard for your needs
KB, MB, GB, TB (1000-based)
Best for: Marketing, storage manufacturers, internet speeds, and general communication
Why? Hard drive manufacturers use this standard (1 TB = 1000 GB). It's what you'll see on product labels and advertisements.
KiB, MiB, GiB, TiB (1024-based)
Best for: Technical work, programming, system administration, and file system reporting
Why? Operating systems use binary calculations (1 GiB = 1024 MiB). This matches how your computer actually measures storage.
Everyday use? Use SI (MB, GB) — it's what most people understand. Technical/programming work? Use IEC (MiB, GiB) for precision. The difference becomes significant with larger files (a 1 TB drive is about 931 GiB).
