So you're saying that the dimension/unit library does *not* need to
worry about formulas like this, right? If so, my comments below are
off-topic.
But I'm still a skeptic. I don't see why the trick I outlined before
can't be played here, too. Tell me what each variable means and what
units it is in (if any). Or give me an online reference for this formula.
