Wouldn't it be better to just present the amount of memory in plain old bytes, so people can use sort -n on it? And it's easier to tell big-from-small at a glance because big has more digits. Also, the first thing any sort of downstream processing of this data is going to have to do is to convert the fancified output back into plain-old-bytes. So why not just emit plain-old-bytes? If someone wants the fancy output (and nobody does) then that can be done in userspace.
