MB to GB Converter
Convert megabytes to gigabytes instantly and free. Enter an MB value and the GB result appears as you type, in both the binary and decimal systems, with nothing to install and no sign up.
Need the other direction? Use GB to MB instead.
Quick answer
To convert MB to GB, divide the megabytes by 1,024. So 4,096 MB is exactly 4 GB. Phone carriers and storage makers divide by 1,000 instead, which turns the same 4,096 MB into 4.096 GB. Both are correct, they simply use different systems, and this MB to GB converter gives you either one.
Is MB greater than GB?
No. GB is the larger unit. One gigabyte holds 1,024 megabytes, so a 900 MB download is still under a single gigabyte. The order runs byte, kilobyte, megabyte, gigabyte, terabyte, with each step roughly a thousand times bigger than the one before it. A quick megabyte to gigabyte conversion is usually all you need to see whether a file fits inside a plan or a drive.
GB = MB ÷ 1024
Binary, used by Windows and macOS. For decimal, divide by 1,000 instead.

Why two different answers exist
Computers count in binary, so an operating system treats one gigabyte as 1,024 megabytes. Storage makers, mobile networks and most upload forms use the decimal meaning of giga, which is 1,000. The strict binary units have their own names, the mebibyte and gibibyte, defined by the IEC binary prefixes. That is what a MiB label means when you meet one, and converting mib to gb uses the same divide by 1,024 rule shown above.
When you actually need this
The usual reason is a plan or a limit. A carrier sells 20 GB a month but reports usage in MB, a game download is quoted at 4,096 MB while your free space reads in GB, or a cloud backup caps a single file. Converting first tells you whether it fits. If it does not, our image compressor and PDF compressor both shrink files without an upload.
