title: sass convert px to vw
body: <p>I found a tutorial on how to write function that converts pixels to vw:</p>
  
  <pre><code>@function get-vw($target) { 
    $vw-context: (1000*.01) * 1px;
    @return ($target/$vw-context) * 1vw;
  }
  </code></pre>
  
  <p>usage on tutorial:</p>
  
  <pre><code>.headline {
    font-size: get-vw(72px);
  }
  </code></pre>
  
  <p>but when I use it like its explained nothing happens
  my browser returns:     </p>
  
  <blockquote>
    <p><strike>font-size: get-vw(44px);</strike>  Invalid property value </p>
  </blockquote>
  
  <p>Since I don't need learn sass at this moment but need only way to convert px to vw can someone help me to make this work?</p>
