Our filesystems are configured as 1024-byte-block systems.  The
'-s' option on 'ls', however, lists the block sizes of files
in number of *512*-byte blocks -- this discrepancy is not noted
in the man page to my knowledge.  Also, the 'find' command states
that its '-size' option takes a number of 512-byte blocks as an
argument, but this is not true.

find /usr/games -size 133 -exec ls -ls {} \;

yields:

 269 -r-x------   1 bin      bin       135920 Apr 11 18:32 cbrogue

Note that 1024 * 133 = 136192; 'find' is obviously using 1024-byte blocks.
No other size will find the file 'cbrogue'.

Anybody know of a rationale for this stuff?

P.S.:  Before anyone points out from the 'ls -ls' that 269 * 512 = 137728;
which is much too large, remember that the '-s' option of 'ls' includes
in its block count the number of indirect blocks as well.
