How to convert megabytes to gigabytes
Converting megabytes (MB) to gigabytes (GB) is simple: divide the megabyte value by the conversion base. The only trick is choosing whether you want the decimal standard or the binary standard.
Formulas
Decimal: GB = MB ÷ 1000
Binary: GiB = MiB ÷ 1024
Decimal vs binary units
In storage marketing (hard drives, SSD labels), decimal units are common. In operating systems and memory tools, binary units are often used. That’s why the same file can appear as slightly different sizes depending on where you view it.
- Decimal system: 1 GB = 1000 MB
- Binary system: 1 GiB = 1024 MiB
- Rule of thumb: Binary values look a bit smaller when converted from MB
