Well, that's not how other tools handle it. I would suggest being consistent
with the rest of the more user friendly unix toolset that does this. GNU dd
for example uses these suffixes:

(Though in this case the base unit is unambiguous because of the parameter.
But other examples are the output of ls -lh, the -c and -n parameters of head,
etc)
