In chemistry and physics, the "Avogadro Constant" is defined as the ratio of the number of constituent particles N in a sample to the amount of substance n through the relationship NA = N/n. Thus, it is the proportionality factor that relates the molar mass of an entity, i.e. , the mass per amount of substance, to the mass of said entity.

The impedance of free space, Z0, is a physical constant relating the magnitudes of the electric and magnetic fields of electromagnetic radiation travelling through free space. That is, Z0 = |E|/|H|, where |E| is the electric field strength and |H| magnetic field strength. It has an exact value, given approximately as 376.73031 ohms. The impedance of free space equals the product of the vacuum permeability or magnetic constant μ0 and the speed of light in vacuum c0. Since the numerical values of the magnetic constant and of the speed of light are fixed by the definitions of the ampere and the metre respectively, the exact value of the impedance of free space is likewise fixed by definition and is not subject to experimental error.

The "Electron Gyromagnetic Ratio" An isolated electron has an angular momentum and a magnetic moment resulting from its spin. While an electron's spin is sometimes visualized as a literal rotation about an axis, it is in fact a fundamentally different, quantum-mechanical phenomenon with no true analogue in classical physics. Consequently, there is no reason to expect the above classical relation to hold.

The \(\textit{Rydberg Constant}\), named after the Swedish physicist Johannes Rydberg, is a physical constant relating to atomic spectra, in the science of spectroscopy.
http://dbpedia.org/resource/Rydberg_constant
The Rydberg constant, symbol R, named after the Swedish physicist Johannes Rydberg, is a physical constant relating to atomic spectra, in the science of spectroscopy. The constant first arose as an empirical fitting parameter in the Rydberg formula for the hydrogen spectral series, but Niels Bohr later showed that its value could be calculated from more fundamental constants, explaining the relationship via his 'Bohr model'. The quantity \(R_y = R_\infty \cdot hc_0\) is called "Rydberg Energy".
