AIX with no human readable ls

I recently had to touch a pretty old AIX OS and it frustrated me not to have human readable output for ls. This function helped a little. An alias did not want to work because of all the quoting going on. Of course as you can notice I changed my shell prior to bash.

  /usr/bin/ls -l "$@" | awk "{\$5=sprintf(\"%.2f GB\", \$5/1024^3)} 1";
}

# alias has to many """ chars to work trying function ls-h
#alias lsh "ls -l \$@ | awk '{$5=sprintf("%.2f GB", $5/1024^3)} 1'"
