Proton Charge to Mass Ratio

$${e\over m_p}=\sqrt{\pi^2{r_p}^2c^3\alpha\epsilon_0\over{2h}}$$

$e=$ elementary electron charge

$m_p=$ proton mass

$r_p=$ proton radius

$c=$ speed of light

$\alpha=$ fine-structure constant

$\epsilon_0=$ permittivity of vacuum

$h=$ Planck's constant

$${e\over m_p}={\pi r_pcq\over{2h}}$$

$e=q=$ elementary charge

(pi*(0.841235640294664e-15)*c*(elementary charge)/2/h)=
