Actually, 1 gigabyte (109 B) is 1000 megabytes (106 B), while one gibibyte (230 B) corresponds to 1024 mebibytes (220 B). I know that in some circles, 1 GB is treated as 1 GiB, so I don’t blame you. This system of quantities is standardised internationally in order to conform with the SI (mega must mean a million times and not 220 times), but many don’t conform to it, such as Microsoft as far as I know.

Thank you for the correction and details.
