Megabytes to gigabytes is needed for phone data plans, file and video sizes, cloud storage and download limits. Storage makers and data plans use decimal units, where 1 GB = 1000 MB, and that is what this page uses. Windows uses binary units (1 GiB = 1024 MiB) but labels them GB, so 1000 MB of files may show as 0.93 GB. Choose MiB and GiB in the converter for those figures.
