title: cURL command units of Dload speed?
body: <p>When I run curl I sometimes see a progress meter like this:</p>
  
  <pre><code>  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                   Dload  Upload   Total   Spent    Left  Speed
   38 11.0M   38 4319k    0     0  20189      0  0:09:31  0:03:39  0:05:52 18472
  </code></pre>
  
  <p>What unit is Average Dload given in?</p>
  
  <p>An answer which also contains a link to another page explaining the entirety of the progress meter (what each section means) would be preferred.</p>
