Formula
How it works: In the decimal system, 1 GB equals exactly 1,000 MB. To convert megabytes to gigabytes, divide the MB value by 1,000. The calculator also shows the reverse (GB to MB) and byte equivalents for reference.
Worked Example
Megabytes to Gigabytes Conversion Explained
Megabytes and gigabytes are the most commonly encountered storage units in daily computing. Understanding the conversion helps with managing downloads, storage devices, and mobile data plans.
- 1 GB = 1,000 MB in the decimal system used by most manufacturers
- 1 GiB = 1,024 MiB in the binary system used by some operating systems
- Internet speeds use megabits (Mb), not megabytes (MB), so divide Mbps by 8 for MB/s
- A typical HD movie is 3,000 to 5,000 MB (3 to 5 GB)
- Most email attachment limits are 25 MB, which is 0.025 GB

Frequently Asked Questions
How many megabytes are in a gigabyte?
In the decimal system, 1 GB = 1,000 MB exactly. In binary, 1 GiB = 1,024 MiB. This calculator uses the decimal standard, which is the same system used by phone carriers, ISPs, and most storage manufacturers.
Is 1,024 MB equal to 1 GB?
Only in the binary system. The decimal standard (used by this tool and most manufacturers) defines 1 GB as exactly 1,000 MB. The binary equivalent is 1 GiB = 1,024 MiB. For everyday use, 1,000 MB per GB is the accepted convention.
How do I know if my file fits on a drive?
Convert your file size to the same unit as the drive capacity. If you have a 750 MB file and 2 GB of free space, divide 750 by 1,000 to get 0.75 GB, which fits easily within 2 GB.
How many MB is a typical phone photo?
A standard smartphone photo is usually 3 to 8 MB depending on camera resolution and compression. A 64 GB phone can store roughly 8,000 to 21,000 photos at these sizes, not counting other apps and system files.
What is the difference between MB and Mb?
MB (uppercase B) stands for megabytes, used for file and storage sizes. Mb (lowercase b) stands for megabits, used for internet speeds. There are 8 megabits in 1 megabyte, so a 100 Mbps connection downloads at about 12.5 MB per second.
