How to convert gigabytes to gibibytes
One gigabyte equals 0.931323 gibibytes, so multiply the number of gigabytes by 0.931323:
GiB = GB × 0.931323
GB = GiB ÷ 0.931323 (1 GiB = 1.0737 GB)
Example: 4.7 GB → 4.7 × 0.931323 = 4.3772 GiB.
Going the other way, divide by 0.931323, or multiply by 1.0737; the gibibytes to gigabytes converter does it for you.
Everyday values
| Gigabytes | Gibibytes | For example |
|---|---|---|
| 4.7 GB | 4.3772 GiB | a DVD (4.38 GiB) |
| 64 GB | 59.6046 GiB | a memory card |
| 500 GB | 465.661 GiB | a 500 GB drive (465.66 GiB) |
| 1,000 GB | 931.323 GiB | a 1 TB drive |
When you need this conversion
Divide GB by 1.0737 to get GiB. Linux tools often label binary units correctly (GiB), while Windows writes "GB" for binary values, which causes most of the confusion.

About the units
- Gigabyte (GB): 1,000,000,000 bytes (SI prefix).
- Gibibyte (GiB): 2³⁰ = 1,073,741,824 bytes (IEC binary prefix).
Both are units of digital storage. The conversion factor comes from the exact definitions above, so the calculator is exact; results are only rounded for display (up to six significant digits).
