Megabytes to Gigabytes Converter
This megabyte to gigabyte converter changes a data size in MB into GB. It loads in the digital category with megabyte as the source and gigabyte as the target, so a file size or data plan figure converts as you type: 1024 MB = 1 GB in the binary convention used by operating systems, while storage vendors often use 1000 MB = 1 GB. The page shows the exact result so you can compare both conventions when a phone plan or disk capacity seems smaller than advertised. It is useful for estimating downloads, cloud quotas, and backup sizes. All calculations run locally in JavaScript; nothing is uploaded or stored. Copy the result with one click.
