Is it weird? Checking the man page for du(1):

DESCRIPTION
The du utility displays the file system block usage for each file
argument and for each directory in the file hierarchy rooted in each
directory argument. Note that the system block usage is usually greater
than the actual size of the file. <snip>

I'm not a file system person, but to me you're looking at different
units here, are you not?
