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
