Assigned width in percentage but want to get it in pixels

Answer 1

Pls check the code appended below, I hope this is the simplest way to get the width from percentage to pixel.

HTML

 
 Perentage to Pixel : 

CSS

 .test {
  border: 1px solid;
  cursor: pointer;
  height: 100%;
  position: relative;
  width: 100%;
  padding: 10px;
}

JS

var widPx = $('#test1').width();
$('#widthPx').append(Math.round(widPx) + 'px');

OUTPUT

Perentage to Pixel : 609px

The output would be purely based on the div width.

Thanks.
