Decimal vs. Binary Units

Storage manufacturers typically use decimal units (1 KB = 1000 bytes), while operating systems often report binary units (1 KiB = 1024 bytes) — which is why a "1 TB" drive shows less than 1 TB of usable space in your file explorer. This converter supports both so you can compare accurately.

Common Use Cases

  • File size checks: Convert file sizes between megabytes and gigabytes before uploading or emailing.
  • Cloud storage plans: Compare storage plan sizes across providers.
  • Bandwidth planning: Convert download sizes to estimate transfer times.
  • Hard drive shopping: Understand advertised vs. actual usable capacity.
