# Physics Constants | ||
|
||
```@contents | ||
Pages = ["units.md","constants.md","convert.md"] | ||
``` | ||
|
||
The following are fundamental constants of physics: | ||
|
||
```math | ||
\alpha = \frac{\lambda e^2}{4\pi\varepsilon_0\hbar c} = | ||
\frac{\lambda c\mu_0 (e\alpha_L)^2}{4\pi\hbar} = | ||
\frac{e^2k_e}{\hbar c} = | ||
\frac{\lambda e^2}{2\mu_0ch} = | ||
\frac{\lambda c\mu_0\alpha_L^2}{2R_K} = | ||
\frac{e^2Z_0}{2h} | ||
``` | ||
|
||
There exists a deep relationship between the fundamental constants, which also makes them very suitable as a basis for `UnitSystem` dimensional analysis. All of the formulas on this page are part of the `Test` suite to guarantee their universal correctness. | ||
|
||
```math | ||
\mu_{eu} = \frac{m_e}{m_u}, \qquad | ||
\mu_{pu} = \frac{m_p}{m_u}, \qquad | ||
\mu_{pe} = \frac{m_p}{m_e}, \qquad | ||
\alpha_\text{inv} = \frac{1}{\alpha}, \qquad | ||
\alpha_G = \left(\frac{m_e}{m_P}\right)^2 | ||
