GB to GiB: exact storage reference table
A decimal GB contains one billion bytes. Divide that byte count by 1,073,741,824 to express the same quantity in GiB. These are equivalent quantities, not missing storage.

Formula & method
B = GB × 10⁹; GiB = B / 2³⁰What can change the answer
Displayed GiB values are rounded. Usable disk capacity also depends on formatting and reserved space, which this unit table does not estimate.
