How to convert gigabytes to gibibytes

Multiply the number of gigabytes by 0.931322575, or divide by 1.07374182.

GiB = GB × 0.931322575  (or GB ÷ 1.07374182)

Example: 1,000 GB × 0.931322575 = 931.323 GiB

This is why a “1 TB” drive shows up as about 931 GB in Windows: the drive holds 1,000,000,000,000 bytes, and Windows divides by 1,073,741,824 (2³⁰) but still writes “GB”.
