Uses binary prefixes (1 KB = 1024 B). For decimal SI (1000-based), multiply or divide mentally.

Common use cases

  • Convert storage quotas between bytes, MB, and GB for product settings.
  • Estimate payload or backup size when planning transfer windows.
  • Cross-check binary unit math in docs and dashboards before publishing.

Common mistakes to avoid

  • Mixing decimal and binary unit conventions

    This page uses 1024-based binary steps. Confirm whether your platform documents decimal or binary units.

  • Comparing values without unit labels

    A raw number is ambiguous. Always include the source unit before converting.

  • Assuming UI labels imply exact byte counts

    Some systems round display values. Use precise unit conversion when accuracy matters.

FAQ

Does this converter use base-10 or base-2?

It uses binary (base-2) progression with 1024 steps between units.

Why do OS values sometimes differ from disk vendor labels?

Many vendors market storage with decimal units, while operating systems often display binary-style conversions. That mismatch creates apparent gaps.

Is conversion done in my browser?

Yes. Unit conversion on this page runs locally in your browser tab.
