Gibibytes to mebibytes
1 gibibyte = 1,024 mebibytes
Type a value in gibibytes (GiB) to get mebibytes (MiB) straight away. A gibibyte is larger than a mebibyte, so the number goes up. Both units belong to data storage, measured here against the byte.
1 GiB = 1,024 MiB
Formula
MiB = GiB × 1,024
One gibibyte is 1,024 mebibytes, so multiply the gibibyte value by that factor. Here GiB is the value in gibibytes and MiB is the result in mebibytes.
Worked example: 16 gibibytes × 1,024 = 16,384 mebibytes.

Quick estimate in your head
Multiply by about 1,000. For 16 GiB that gives 16,000 MiB against an exact 16,384 MiB, an error of 2.3%.
Watch out for
- A GiB is 7.37% larger than a GB. RAM is sized in GiB even when the label says GB.
- A MiB is 4.86% larger than a MB. Older software labels MiB as MB.
About the units
Gibibyte (GiB). 2³⁰ bytes, about 7.4% more than a GB. RAM is sized in GiB.
Mebibyte (MiB). 2²⁰ = 1,048,576 bytes. The binary unit behind most memory and OS file sizes.
Going the other way, 1 mebibyte is 0.000976563 gibibytes.
Questions
How many mebibytes are in 1 gibibyte?
1 gibibyte is 1,024 mebibytes, and 1 mebibyte is 0.000976563 gibibytes.
How do I convert gibibytes to mebibytes?
Use MiB = GiB × 1,024. For example, 16 gibibytes × 1,024 = 16,384 mebibytes.
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 a workstation's RAM in mebibytes?
64 GiB is 65,536 MiB.
