A megabyte is 1,000 kilobytes or 1,000,000 bytes using the SI decimal standard.
View the megabyte data unit pageHow to Convert Gibibytes to Megabytes
To convert gibibytes (binary/IEC) to megabytes (decimal/SI), multiply by 1,073.741824. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales.
GiB is a binary (IEC) unit where 1 GiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations.
MB is a decimal (SI) unit where 1 MB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Related: Gibibytes to Bits.
1 GiB = 1,073.741824 MB (using SI decimal standard) — which means there are 1,073.741824megabytes in every gibibyte.

SI Decimal vs Binary: Why Two Different Standards?
When converting gibibytes to megabytes, 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 above the converter.
FAQs: Gibibyte to Megabyte Conversion
How many megabytes are in 1 gibibyte?
1 Gibibyte (GiB) equals 1,073.741824 Megabytes using the SI decimal standard.
