A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use.
View the gigabyte data unit pageHow to Convert Megabytes to Gigabytes
To convert megabytes to gigabytes, divide by 1,000 (using SI decimal). Both units measure storage capacity—the difference is scale.
MB: A megabyte is 1,000 kilobytes or 1,000,000 bytes using the SI decimal standard.
GB: A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use.
1 MB = 0.001 GB (using SI decimal standard) — or equivalently, 1 GB = 1,000MB.
MB to GB conversion rate: 1 megabyte equals 0.001gigabytes — the standard megabyte to gigabyte data storage conversion used by this calculator.

MB to GB Conversion Formula
Here's the exact MB to GB formula in copy-paste-ready form — multiply by 0.001 to go from megabytes to gigabytes, or by 1,000 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert MB to GB
GB = MB × 0.001
// Reverse: Convert GB to MB
MB = GB × 1,000
Megabyte to Gigabyte Conversion Examples
100 MB = 0.1 GB
256 MB = 0.256 GB
500 MB = 0.5 GB
1,000 MB = 1 GB
2,048 MB = 2.048 GB
Binary Standard (Base 1024)
Using binary calculation: 1 MB = 0.0009765625 GB
100 MB = 0.09765625 GB
1,000 MB = 0.9765625 GB

SI Decimal vs Binary: Why Two Different Standards?
When converting megabytes to gigabytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard above the converter.
Want to skip the ambiguity entirely? Mebibyte (MiB) and Gibibyte (GiB) are the IEC binary-only siblings of megabyte and gigabyte — always base 1,024, no dual-standard guessing. See the MiB to GiB converter.
FAQs: Megabyte to Gigabyte Conversion
How many gigabytes are in 1 megabyte?
1 Megabyte (MB) equals 0.001 Gigabytes using the SI decimal standard, or 0.0009765625 GB using the binary (IEC) standard.
How do I convert megabytes to gigabytes?
Multiply the megabyte value by 0.001 to get gigabytes. For example, 10 MB = 0.01 GB.
Is a megabyte bigger than a gigabyte?
No. 1 MB = 0.001 GB, so the gigabyte is larger — 1 GB = 1,000 MB.
What is Megabyte (MB) commonly used for?
MP3 files, high-resolution images, short video clips, software installers.
