How to convert MB to GB
megabytes × 0.001 = gigabytes
This uses the decimal definition, 1000 MB to the GB, which is what drive manufacturers use. Operating systems often divide by 1024 instead and report the same drive as smaller — that gap, not a missing chunk of disk, is why a "1 TB" drive shows up as 931 GB.

What a megabyte and a gigabyte are
Both are units of data, which is what makes them convertible at all: the converter above works by taking your value to a single reference unit for that family and back out again, so the figure it gives is the same one the table shows, carried to more digits. Nothing is sent anywhere to compute it — the arithmetic runs in this page, in your browser.
