How to Convert Mebibytes to Gigabytes
To convert mebibytes (binary/IEC) to gigabytes (decimal/SI), multiply by 0.001048576. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales. Learn more: Gigabytes in Mebibytes.
MiB is a binary (IEC) unit where 1 MiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations. Learn more: converting Mebibytes to Exbibits.
GB is a decimal (SI) unit where 1 GB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Learn more: KiB to GB conversion rate.
1 MiB = 0.001048576 GB (using SI decimal standard) — or equivalently, 1 GB = 953.6743164063MiB.
MiB to GB Conversion Formula
// Convert MiB to GB
GB = MiB × 0.001048576
// Reverse: Convert GB to MiB
MiB = GB × 953.6743164063
Mebibyte to Gigabyte Conversion Examples
100 MiB = 0.1048576 GB

SI Decimal vs Binary: Why Two Different Standards?
When converting mebibytes to gigabytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
