How the Megabytes to Gigabytes Converter works
In the SI (decimal) system used by drive makers and mobile data plans, 1 GB = 1,000 MB. Operating systems sometimes use binary units, where 1 GiB = 1,024 MiB, which is why a drive can show less space than advertised.
To convert megabytes to gigabytes, multiply by 0.001. The calculator shows the result to 6 significant figures; the conversion factor itself is exact by definition.
Quick estimate in your head: move the decimal point three places left.
The formula
Worked example
Using the default values shown in the calculator:
| Value in megabytes (MB) | 1500 |

| Gigabytes (GB) | 1.5 |
|---|---|
| 1 MB in GB | 0.001 |
| Your number read as GB, in MB | 1500000 |
| Gibibytes (binary) (GiB) | 1.39698 |
| Kilobytes (kB) | 1500000 |
