Possible to use 'du' command along with 'ls'?

Is it possible to use du command along with ls, so i can get better information what are folders and what are files, and info about ownership and permissions? Something like ls usage in Find command: find ~/ -ls

Also, in this listing i see files with kilobytes size in front of files with megabytes size. Why is that? I assume 'K' stands for kilobytes and 'M' stands for megabytes:

max@ubuntu:/var/cache$ sudo du -sh * | sort -nr
93M     apt-xapian-index
50M     apt
32K     fontconfig
20K     ldconfig
8.0K    dbconfig-common
8.0K    apache2
4.9M    debconf
4.0K    pppconfig
4.0K    apparmor
1.3M    man
