FreeBSD 6.2:
-g Use 1073741824-byte (1-Gbyte) blocks rather than the default.
Note that this overrides the BLOCKSIZE specification from the
environment.
NetApp ONTAP 7.2.5.1:
The -h option scales the units of each size-related field
to be KB, MB, GB, or TB, whichever is most appropriate for
the value being displayed. The -k, -m, -g, and -t options
scale each size-related field of the output to be
expressed in kilobytes, megabytes, gigabytes, or terabytes
respectively. Unit values are based on powers of two.
For example, one megabyte is equal to 1,048,576 bytes.
AIX doesn't specify a number in -g:
-g
Displays statistics in units of GB blocks. The output values for
the file system statistics would be in floating point numbers as
value of each unit in bytes is significantly high.
but it DOES in -k:
-k
Displays statistics in units of 1024-byte blocks.
So, it looks to be 2's based everywhere I have to refer against.
