Convert gigabytes to gibibytes
gibibytes = gigabytes × 0.931323
One gigabyte is 0.931323 gibibytes, so multiply by 0.931323 to convert. Going the other way, one gibibyte is 1.0737 gigabytes. This is the conversion behind a drive that seems to lose space: manufacturers sell decimal units (1 TB = 10¹² bytes) while Windows displays binary ones (1 TiB = 2⁴⁰ bytes) under the label “TB”. Nothing is missing — the same bytes are being counted in a bigger unit.
