For the moment in http://dev.w3.org/csswg/cssom/

We can find

interface ViewCSS {
  CSSStyleDeclaration getComputedStyle(in Element elt);
  CSSStyleDeclaration getComputedStyle(in Element elt, in DOMString
The getComputedStyle method must return a live CSSStyleDeclaration object
that contains the computed style declaration block for elt, when the
pseudoElt argument is null, the empty string or omitted. Otherwise, for the
pseudo-element pseudoElt of elt. [CSS]

And then
interface CSSStyleDeclaration {
           attribute DOMString cssText;
  DOMString getPropertyValue(in DOMString property);
  DOMString getPropertyPriority(in DOMString property);
  DOMString removeProperty(in DOMString property);
  void setProperty(in DOMString property, in DOMString value);
  void setProperty(in DOMString property, in DOMString value, in DOMString
  readonly attribute unsigned long length;
  DOMString item(in unsigned long index);
  readonly attribute CSSRule parentRule;

So it means, if I want to have access to the width of an element
getComputedStyle(el, "").getPropertyValue("width");

I propose to add a new parameter to getPropertyValue so that you can choose
the unit

something like

getComputedStyle(el, "").getPropertyValue("width", "px");

And even to get information with respect to relative value

getComputedStyle(el, "").getPropertyValue("width", "em");
