title: Converting MM:SS.ms to seconds using MS excel
body: <p>I am looking for a neat way of converting a cell from</p>
  
  <p><code>Minutes:Seconds.Milliseconds</code> to</p>
  
  <p><code>Seconds.Milliseconds</code></p>
  
  <p>i.e. </p>
  
  <pre><code>11.111    = 11.111
  1:11.111  = 71.111
  </code></pre>
  
  <p>I have something in place at the moment but its a bit hacky and I am sure there must be some nice excel feature to do this for me :P</p>
  
  <p>Thanks!</p>
