Mebibytes to gibibytes
1 mebibyte = 0.000976563 gibibytes
Type a value in mebibytes (MiB) to get gibibytes (GiB) straight away. A mebibyte is smaller than a gibibyte, so the number goes down. Both units belong to data storage, measured here against the byte.
1 MiB = 0.0009765625 GiB
Formula
GiB = MiB × 0.0009765625
One mebibyte is 0.0009765625 gibibytes, so multiply by that factor. You can also divide by 1,024, the number of mebibytes in one gibibyte. Here MiB is the value in mebibytes and GiB is the result in gibibytes.
Worked example: 100 mebibytes × 0.0009765625 = 0.0976563 gibibytes.

Quick estimate in your head
Multiply by about 0.00098. For 100 MiB that gives 0.098 GiB against an exact 0.0976563 GiB, an error of 0.4%.
Watch out for
- A MiB is 4.86% larger than a MB. Older software labels MiB as MB.
- A GiB is 7.37% larger than a GB. RAM is sized in GiB even when the label says GB.
About the units
Mebibyte (MiB). 2²⁰ = 1,048,576 bytes. The binary unit behind most memory and OS file sizes.
Gibibyte (GiB). 2³⁰ bytes, about 7.4% more than a GB. RAM is sized in GiB.
Going the other way, 1 gibibyte is 1,024 mebibytes.
Questions
How many gibibytes are in 1 mebibyte?
1 mebibyte is 0.000976563 gibibytes, and 1 gibibyte is 1,024 mebibytes.
How do I convert mebibytes to gibibytes?
Use GiB = MiB × 0.0009765625. For example, 100 mebibytes × 0.0009765625 = 0.0976563 gibibytes.
Why does my drive show less space than advertised?
Makers use decimal units (1 GB = 10⁹ bytes) while many operating systems count in binary (1 GiB = 2³⁰ bytes). A 1 TB drive therefore shows about 931 GiB.
How much is one GiB in gibibytes?
1,024 MiB is 1 GiB.
