The prior poster didn't get 1048576 from either definition of "gigabyte":

2^20 = 1048576 (the old meaning of "megabyte", and see below), but

one gigabyte = either 10^9 (1,000,000,000) or 2^30 (1,073,741,824).

There are a bunch of ways to get these values in a script, based on
arbitrary input units.

Also see:

$ units gigabyte
Definition: 1e9 byte = 8e+09 bit

$ units megabyte
Definition: 1e6 byte = 8000000 bit

These definitions changed only recently.
