Convert mebibytes to gibibytes

1 mebibyte = 0.000977 gibibytes

gibibytes = mebibytes × 0.000977

One mebibyte is 0.000977 gibibytes, so multiply by 0.000977 to convert. That factor is exact by definition. KiB, MiB, GiB and TiB are the IEC binary units: every step is ×1,024. Windows and RAM specs count this way; drive makers and macOS use the decimal MB/GB/TB of 1,000.
