How to Convert Gibibyte to Kibibyte
- 1 GiB = 1048576 KiB
- 1 KiB = 9.536743164 × 10⁻⁷ GiB
- Example: convert 15 GiB to KiB: 15 GiB = 15 × 1048576 KiB = 15728640 KiB
Formula
KiB = GiB × 1048576
Derivation from SI units:
- 1 GiB = 2³⁰ bytes = 1,073,741,824 bytes.
- 1 KiB = 2¹⁰ bytes = 1024 bytes.
- 1 GiB = 8589934592 bit ÷ 8192 bit per KiB = 1048576 KiB
Both units are defined exactly, so the factor is exact. Gibibyte definition: gibibyte; Kibibyte definition: kibibyte.
Worked examples
- A reading of 16 GiB converts to 16777216 KiB.
16 GiB × 1048576 = 16777216 KiB - A value of 128 GiB is 134217728 KiB.
128 GiB × 1048576 = 134217728 KiB
