How to Convert Gibibyte to Byte
- 1 GiB = 1073741824 B
- 1 B = 9.313225746 × 10⁻¹⁰ GiB
- Example: convert 15 GiB to B: 15 GiB = 15 × 1073741824 B = 16106127360 B
Formula
B = GiB × 1073741824
Derivation from SI units:
- 1 GiB = 2³⁰ bytes = 1,073,741,824 bytes.
- 1 byte = 8 bits (an octet).
- 1 GiB = 8589934592 bit ÷ 8 bit per B = 1073741824 B
Both units are defined exactly, so the factor is exact. Gibibyte definition: gibibyte; Byte definition: byte.
Worked examples
- A reading of 16 GiB converts to 17179869180 B.
16 GiB × 1073741824 = 17179869180 B - A value of 128 GiB is 137438953500 B.
128 GiB × 1073741824 = 137438953500 B
