MB / MiB / GB / GiB Converter
Convert storage units across decimal and binary measurement systems with practical MB, MiB, GB, and GiB comparisons.
Input
Convert storage values across decimal and binary unit systems without mixing up MB, MiB, GB, and GiB.
Result
Normalized conversions across decimal and binary storage units with a practical summary.
What this means
The current input of 1.000000 GiB has been converted across decimal and binary storage units from the same byte value.
MB and GB are decimal units based on powers of 1000, while MiB and GiB are binary units based on powers of 1024. The current decimal-versus-binary spread is 6.867743% at this scale.
Use this when comparing vendor capacity, OS-reported values, storage estimates, or documentation that mixes decimal and binary units. Treating them as identical is sloppy and creates bad assumptions.
Common presets
Storage unit quick guide
Decimal and binary units are not interchangeable, and pretending they are is how capacity estimates drift.
Decimal units
MB and GB use powers of 1000. Vendors and network-style references often use decimal sizing.
Binary units
MiB and GiB use powers of 1024. Operating systems and technical tooling often expose binary values.
Why it matters
The difference is small at low values and more noticeable at scale. Sloppy conversions create bad storage assumptions.
