Oh, ok.

I'm sorry. I've just never seen anything like that before, so I had no visual reference for it. >_< I'm not any good at imagining certain things in my head- anything involving measurements is well beyond me. I have some kind of learning disability in that area. 

I'm being serious about that, though... When someone starts talking inches, kilometers, ounces, even money... all that stuff, I just have no understanding of any of it.
