How to convert megabytes to gigabytes
Apply the documented megabytes-to-gigabytes relationship below, keeping the full stored constant until the displayed result is rounded.
Megabytes × 0.001 = Gigabytes
For example, 10 MB equals 0.01 GB.
Megabytes to Gigabytes reference table
| Megabytes | Gigabytes |
|---|---|
| 1 MB | 0.001 GB |
| 5 MB | 0.005 GB |
| 10 MB | 0.01 GB |
| 25 MB | 0.025 GB |
| 50 MB | 0.05 GB |
| 100 MB | 0.1 GB |
Method and quality checks
- Calculation
- Megabytes × 0.001 = Gigabytes. The calculator keeps the stored factor through the operation and rounds only the displayed result to the selected or page-supported precision.
- Unit convention
- Decimal SI storage units are used: 1 GB equals 1,000 MB. Binary units such as GiB and MiB are separate units.
- Input validation
- Finite numeric inputs are accepted. Results outside the supported numeric range are rejected instead of being displayed as valid measurements.
- Reasonableness check
- 10 MB produces 0.01 GB. Check the direction and approximate scale before relying on a more precise displayed value.

Moving from decimal megabytes to gigabytes
This converter follows decimal storage prefixes, where one gigabyte equals exactly 1,000 megabytes. Binary mebibytes and gibibytes use powers of 1,024 and must be labeled MiB and GiB instead.
- Use uppercase B for bytes; lowercase b denotes bits.
- Confirm whether software reports decimal MB or binary MiB.
- File-system overhead and reserved space can make usable capacity lower than the nominal value.
