MB to GB Conversion Calculator is an online tool for digital computation to perform the conversion either from megabytes to gigabytes or from gigabytes to megabytes. In digital computation the file size is usually measured in kilobytes, megabytes and gigabytes. In order to perform the conversion from MB to GB, enter the value of the file size in Megabytes form field. It will automatically generate the output value in Gigabytes. The equivalent file size in megabytes is also calculated by this same calculator by entering the input file size in the gigabyte's form field which produce the resulting output in megabytes. This MB to GB conversion calculator is also applicable to calculate the bandwidth in both the units by giving either size as input.
