How to convert gibibytes to gigabytes
One gibibyte equals 1.0737 gigabytes, so multiply the number of gibibytes by 1.0737:
GB = GiB × 1.0737
GiB = GB ÷ 1.0737 (1 GB = 0.931323 GiB)
Example: 4 GiB → 4 × 1.0737 = 4.295 GB.
Going the other way, divide by 1.0737, or multiply by 0.931323; the gigabytes to gibibytes converter does it for you.
Everyday values
| Gibibytes | Gigabytes | For example |
|---|---|---|
| 1 GiB | 1.0737 GB | one gibibyte |
| 4 GiB | 4.295 GB | 4 GiB of RAM |
| 8 GiB | 8.5899 GB | 8 GiB of RAM |
| 16 GiB | 17.1799 GB | 16 GiB of RAM |
When you need this conversion
One GiB (gibibyte) is 1,073,741,824 bytes, about 7.4% more than one GB. Memory (RAM) is built in binary sizes, so "16 GB of RAM" is really 16 GiB, or 17.18 GB.

About the units
- Gibibyte (GiB): 2³⁰ = 1,073,741,824 bytes (IEC binary prefix).
- Gigabyte (GB): 1,000,000,000 bytes (SI 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).
