Avogadro's Constant

	Which is it, Avogadro's Constant or Avogadro's Number?
	The National Institute of Standards and Technology (NIST) calls it a constant, as do several other standards organizations.

The International Union of Pure and Applied Chemistry (IUPAC) defines a mole as the number of atoms in 12 grams of carbon-12. The 1998 CODATA recommended value¹ for this number is 6.02214199 x 10²³ and this is what the National Institute of Standards and Technology (NIST) currently uses.

In general, Avogadro's Number, often designated N_A, is the "number of atoms needed such that the number of grams of a substance equals the atomic mass of the substance".

In other words, 6.02214199 x 10²³ amu equals one gram.

The molecular weight, in atomic mass units (amu),

OK, so I'm a moron for putting up this page long before it's ready for prime time. But I have a great vision that one day it will actually be finished and complete. Please share in this delusion.

The mole is the only fundamental unit in the International System of Units (SI) that has no dimension.

On the other hand, the clear winner of the googlefight matchup is Avogadro's Number, by a 5 to 3 margin. Which just goes to show that it probably doesn't matter.

	Why do some call it Agravado's Number or Avocado's Number?
	Some sort of social commentary, perhaps?
