Copmare to what the system's ls(1) does:
ls -s
BLOCKSIZE=512 ls -s
BLOCKSIZE=4096 ls -s
Repeat for 'ls -l'.
Also see the details of the 'Long Format' section in the manual page:
| In addition, for each directory whose contents are displayed, the total
| number of 512-byte blocks used by the files in the directory is
| displayed on a line by itself, immediately before the information for
| the files in the directory.
