title: Linux du directory size, how is this possible?
body: <p>I have a folder called joblibSCRATCH.  I do and see this</p>
  
  <pre><code>ubuntu@memo:~$ du -s joblibSCRATCH
  2831128 joblibSCRATCH
  </code></pre>
  
  <p>This is 2831128 kilobytes, which is 2.836024GB.  I then do and see this</p>
  
  <pre><code>ubuntu@memo:~$ du -hs joblibSCRATCH
  2.7G    joblibSCRATCH
  </code></pre>
  
  <p>So du is saying that this folder is both 2.7GB and 2.83 GB.  How can this be?  If it makes any difference I'm using a virtual hard drive on a cloud server.</p>
