GB to GiB
Compare decimal device capacities with binary quantities. GB and GiB are intentionally different.
Edit either value. Use a decimal point; commas group thousands. Rounding affects display only.
How to convert gigabytes (decimal) to gibibytes (binary)
Compare decimal device capacities with binary quantities. GB and GiB are intentionally different.
Formula coefficients shown rounded. Calculations use the stored factors before display rounding.
A worked example
For 10 GB, the result is approximately 9.313225746 GiB. To go the other way, edit the result above or swap the units.
Decimal kB, MB and GB use powers of 1000. Binary KiB, MiB and GiB use powers of 1024. One byte is eight bits.
