Result

Normalized conversions across decimal and binary storage units with a practical summary.

Input 1.000000 GiB
MB 1,073.741824 MB
MiB 1,024.000000 MiB
GB 1.073742 GB
GiB 1.000000 GiB
Difference note 6.867743% decimal/binary spread

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.
