I thought that was one of the points of this interface, was that you could convert anything to px by getting the ".px" of its property value. Are you saying that should not be the case when it is myElem.style? Or are automatic conversions between absolute units (inches, cm, px) OK?

Hopefully that would work, even if the .style version didn't. But I like the idea of converting as if there was a calc().
