Tip: Use binary when comparing OS file sizes or RAM.
Formula used
There are two widely-used definitions for converting megabytes to larger units:
- Decimal (SI): 1 GB = 1000 MB. Therefore, GB = MB ÷ 1000.
- Binary (IEC): 1 GiB = 1024 MiB. Therefore, GiB = MiB ÷ 1024. If your inputs are labeled MB from devices using decimal marketing, the binary result is an approximation.
Storage vendors commonly use decimal; operating systems often display binary.
How to use this calculator
- Enter a single MB value or paste multiple values.
- Pick Decimal for vendor specs; pick Binary for OS/RAM.
- Set decimal places and rounding strategy for the outputs.
- Choose thousands separator for easier reading.
- Click Convert & Render to produce the table below.
- Download the table as CSV or PDF for documentation.

Reverse Conversion: GB to MB (Decimal)
Convert GB back to MB using the decimal standard (1 GB = 1000 MB).
| Input (GB) | Output (MB) |
|---|---|
| 0.100 | 100 |
| 0.500 | 500 |
| 1.000 | 1,000 |
| 2.000 | 2,000 |
| 5.000 | 5,000 |
| 10.000 | 10,000 |
| 50.000 | 50,000 |
| 100.000 | 100,000 |
Binary reverse tip: multiply GiB by 1024 to get MiB.
FAQs
No. MB is decimal (10^6 bytes) and MiB is binary (2^20 bytes). This tool supports both conventions when converting to larger units.
Use decimal for vendor-stated capacities like SSDs or memory cards. Use binary for operating system file sizes and RAM comparisons to avoid confusion.
No. Rounding only affects how you display the number. Choose more decimals for precision or fewer for simplicity; the input remains the same.
Yes. Paste one value per line in Batch values, convert, then use Download CSV or Download PDF to save the generated table.
Many devices advertise capacity in decimal. Operating systems frequently report using binary, which yields smaller numeric values for the same underlying bytes.
Yes. Multiply by 1000 for decimal GB to MB, or by 1024 for binary GiB to MiB. This reverses the formulas used on this page.
