Reminds me of someone's script I have been using for over a decade.

    #/bin/sh
    du -k --max-depth=1 "$@" | sort -nr | awk '
         BEGIN {
            split("KB,MB,GB,TB", Units, ",");
         }
         {
            u = 1;
            while ($1 >= 1024) {
               $1 = $1 / 1024;
               u += 1
            }
            $1 = sprintf("%.1f %s", $1, Units[u]);
            print $0;
         }
        '
