{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
Link for Google Calculation of charge to mass ratio of proton
elementary charge / proton mass =
95 788 332.2 s A / kg
(elementary charge)/m_p=
First! (?)
Still first, no one else has this equation.
