title: MVC3 - 3 decimal places on type double with leading zero
body: <p>I have a field for <strong>weight in Kgs</strong> (type double or use something else??).
  In edit view I would like the user to enter numbers to the <strong>thousandth place</strong>.
  In display view I would like the Kgs to appear like 560.250</p>
  
  <p>Trying to learn MVC3 + Razor.
  Willing to explore JQuery, use of regular expressions, validators, view templates, view models...</p>
  
  <p>The "magic" of MVC based on conventions takes getting used to.  Confused as to which approach to use.</p>
  
  <p>Thank you in advance for your help. </p>
