How to Convert Gibibyte to Gigabyte
- 1 GiB = 1.073741824 GB
- 1 GB = 0.9313225746 GiB
- Example: convert 16 GiB to GB: 16 GiB = 16 × 1.073741824 GB = 17.17986918 GB
Formula
GB = GiB × 1.073741824
Derivation from SI units:
- 1 GiB = 2³⁰ bytes = 1,073,741,824 bytes.
- 1 GB = 10⁹ bytes = 8 × 10⁹ bits (decimal, SI).
- 1 GiB = 8589934592 bit ÷ 8000000000 bit per GB = 1.073741824 GB
Both units are defined exactly, so the factor is exact. Gibibyte definition: gibibyte; Gigabyte definition: gigabyte.
Worked examples
- 16 GiB of RAM is 17.17986918 GB.
16 GiB × 1.073741824 = 17.17986918 GB - A 100 GiB cloud disk is 107.3741824 GB.
100 GiB × 1.073741824 = 107.3741824 GB
