Convert Gigabytes to Megabytes
Enter a value in gigabytes (GB) to instantly calculate the equivalent value in megabytes (MB).
Formula: megabytes = gigabytes × 1,000
How to Convert Gigabytes to Megabytes
To convert gigabytes (GB) to megabytes (MB), multiply the number of gigabytes by 1,000.
Formula:
MB = GB × 1,000
Example – to convert 2.5 GB to MB:
2.5 × 1,000 = 2,500 MB
Therefore:
2.5 GB = 2,500 MB
This converter uses the decimal standard, where 1 GB = 1,000 MB. Binary storage units use different terminology: 1 GiB = 1,024 MiB.

Frequently Asked Questions About Gigabytes to Megabytes
How do you convert gigabytes to megabytes?
Multiply the number of gigabytes (GB) by 1,000 to convert it to megabytes (MB).
How many megabytes are in 1 gigabyte?
Using the decimal standard, 1 GB = 1,000 MB.
How many megabytes is 0.5 GB?
0.5 GB = 500 MB.
How many megabytes is 2.5 GB?
2.5 GB = 2,500 MB.
Why do some sources say 1 GB equals 1,024 MB?
That comes from older binary conventions. Under standardized terminology, GB and MB are decimal units, while GiB and MiB are binary units.
What is the difference between GB and MB?
Both measure digital data and storage capacity, but a gigabyte represents a larger amount of data than a megabyte.

About Gigabytes and Megabytes
A gigabyte (GB) is a unit used to measure digital information and storage capacity. Under the decimal convention used by this converter, 1 GB equals 1,000,000,000 bytes. Gigabytes are commonly used to describe the storage capacity of computers, smartphones, memory cards, drives, software, and larger digital files.
Megabytes (MB)
A megabyte (MB) is a smaller unit of digital information and storage capacity. Under the decimal convention, 1 MB equals 1,000,000 bytes, and 1 GB equals 1,000 MB. Megabytes are commonly used for documents, photographs, audio files, smaller software downloads, and individual digital files.
1 GB = 1,000 MB.
For additional information about metric measurement and SI units, visit the U.S. National Institute of Standards and Technology (NIST).
Understanding the difference between decimal and binary digital-storage units is important when comparing storage capacities and file sizes. This converter follows the decimal convention, where 1 GB = 1,000 MB. Binary units use different names: gibibyte (GiB) and mebibyte (MiB), with 1 GiB = 1,024 MiB. Recognizing this distinction can help explain why storage measurements may sometimes appear different across operating systems, software, and hardware specifications.
Using our gigabytes to megabytes converter also helps keep your calculations consistent with the decimal GB and MB standard used throughout this page.
For fast and accurate results, use our gigabytes to megabytes converter whenever you need to compare digital storage or data measurements between gigabytes (GB) and megabytes (MB).
