How to Convert Gibibyte to Mebibyte
- 1 GiB = 1024 MiB
- 1 MiB = 0.0009765625 GiB
- Example: convert 15 GiB to MiB: 15 GiB = 15 × 1024 MiB = 15360 MiB
Formula
MiB = GiB × 1024
Derivation from SI units:
- 1 GiB = 2³⁰ bytes = 1,073,741,824 bytes.
- 1 MiB = 2²⁰ bytes = 1,048,576 bytes.
- 1 GiB = 8589934592 bit ÷ 8388608 bit per MiB = 1024 MiB
Both units are defined exactly, so the factor is exact. Gibibyte definition: gibibyte; Mebibyte definition: mebibyte.
Worked examples
- A reading of 16 GiB converts to 16384 MiB.
16 GiB × 1024 = 16384 MiB - A value of 128 GiB is 131072 MiB.
128 GiB × 1024 = 131072 MiB
