How this is calculated
This uses the decimal (SI) standard that storage vendors and network tools use, where 1 gigabyte equals 1000 megabytes and 1 megabyte equals 1000 kilobytes. Megabytes are divided by 1000 to get gigabytes. Operating systems that report sizes in binary units (1 GiB = 1024 MiB) will show slightly smaller numbers for the same bytes.
