title: naming conventions for constants and their units
body: <p>Should the names of my constants incorporate the units that it represents, or is this better handled by a short comment?  Sometimes the constant names can become lengthy.  For example, I can choose between:</p>
  
  <pre><code>// Seconds spent displaying logo
  public static final float LOGO_DISPLAY_TIMER = 1.5f;
  </code></pre>
  
  <p>and </p>
  
  <pre><code>public static final float LOGO_DISPLAY_TIMER_IN_SECONDS = 1.5f;
  </code></pre>
  
  <p>I've been reading <a href="http://www.amazon.co.uk/Clean-Code-Handbook-Software-Craftsmanship/dp/0132350882" rel="nofollow noreferrer">Clean code</a>, which places great emphasis on accurate naming conventions, but I wasn't sure about this specific case.</p>
