Fuel usage per distance travelled is in liters/kilometer. In base SI units that would be m[sup]3[/sup]/m = m[sup]2[/sup] and can easily be converted to hectares. Of course, we usually measure kilometerage (is that a word?) in kilometers per liter so perhaps I should have said hectares[sup]-1[/sup].
Ah, that’s interesting - I never thought about it like that. Cool. I admit that I was misreading your post:
[ul]compute your fuel usage per (distance travelled in hectares).[/ul]instead of:
[ul]compute your (fuel usage per distance travelled) in hectares.[/ul]Stupid language.
As for the GR thing, like I said, I can’t explain it, but I do want to apologize for using “Universe” for “observable Universe” - I never really understood the distinction between the two. Also, when I referred to the Universe’s “upper size limit” I should have used the term “current upper size limit”. As I understand it, the size of the (observable) Universe is only a constant in the same respect that Hubble’s Constant is a constant.
Er, the Hubble Constant. Not Hubble’s Constant. Sorry for any confusion potential.
