In the digital storage, 1 gigabyte (GB) is 1000 megabytes (MB) in the standard decimal system employed by most of the storage vendors. In certain computer systems that employ the binary system, however, 1GB may be equal to 1,024MB. Units such as Gigabyte and Megabyte are used to measure file sizes, memory, and storage capacity of such devices as computers, smartphones, and hard drives.
