Disk test display feature request

A feature request for you.
Most unix-like operating systems now support the -h switch on the df
I am sure I do not need to tell you, -h displays the output in human
# df -h
Filesystem size used avail capacity Mounted on
/dev/vx/dsk/bootdg/rootvol 7.9G 3.3G 4.5G 43% /
swap 7.9G 1.4M 7.9G 1%
/dev/vx/dsk/bootdg/var 7.9G 4.5G 3.3G 58% /var

/dev/vx/dsk/6540b/dsu4 7.3T 5.2T 2.1T 72%
Not so good if you want to do calculations, but far more readable
# df -k

Is it possible to have the calculations and graphs based on the standard
df -k output, but have the display use df -h?
It might require 2 iterations of the df command at client level, one for
display, and another for data.
I was thinking, maybe even add another definition in the client configs.
DF_DISP="df -h", which would then allow any switches to be added,
depending on preference.
I have tried changing the DF= command definition to df -h in the config,
but that seems to break some of the calculations at server side.
