Convert megabytes to gigabytes instantly using decimal units, where one gigabyte is 1000 megabytes. This is the conversion for sizing downloads, data caps, backups, and file collections when a total is given in megabytes but you want the tidier gigabyte figure. Type any number of megabytes and the gigabyte value updates live as you type. This page uses the decimal (SI) system that drive makers and internet providers use, so 1 GB is 1000 MB rather than the binary 1024 MB that some operating systems apply, which is why reported sizes sometimes differ slightly. Dividing by 1000 is simple, but the tool removes the risk of a misplaced decimal on large figures. It runs in your browser, so it is instant, private, and works offline once the page has loaded.
