For example, 10 GB equals 10,000 MB.
Gigabytes to Megabytes reference table
| Gigabytes | Megabytes |
|---|---|
| 1 GB | 1,000 MB |
| 5 GB | 5,000 MB |
| 10 GB | 10,000 MB |
| 25 GB | 25,000 MB |
| 50 GB | 50,000 MB |
| 100 GB | 100,000 MB |
Understanding the result
Keep extra decimal places while you work, then round once at the end. For everyday use, two to four decimal places is usually enough. Scientific, engineering, and regulated work may require a specified precision or reference standard.
These pages use decimal storage units: 1 GB equals 1,000 MB. Some operating systems also use binary units such as GiB and MiB, which are different.
Decimal GB and MB versus binary GiB and MiB
This converter follows decimal SI prefixes used by storage manufacturers: 1 GB = 1,000 MB. Binary quantities use the distinct symbols GiB and MiB and scale by 1,024 instead.
- Keep the B uppercase for bytes; lowercase b means bits.
- Check whether an operating system reports GB or GiB.
- Advertised capacity and available formatted capacity are not identical concepts.
Reference: IEC binary prefixes.
