Avogadro Constant Fundamental Physical Constant

AvogadroConstant is a natural constant and implemented as a UniqueConstant. Its value [Cohen/Cvitas/etal_2007] (p.111) (see also [Cohen/Cvitas/etal_2007] (p. 45)) is an experimental value. Its numerical value is 6.02214179 mol^-1.

The dimension of AvogadroConstant is .

AvogadroConstant defines the following units:

• OnePerMole (composed) and prefix variants

The constant should be used as a macro AVOGADROCONSTANT:

std::cout << " L = " << AVOGADROCONSTANT << std::endl;   // prints the Avogadro constant

AvogadroConstant is a Loki::Singleton, defined in namespace avogadroConstant.
