Proton to Electron Mass Ratio

Physical Law
The ratio of the mass of the proton to the mass of an electron is given by:
 * $\dfrac {m_{\mathrm p} } {m_{\mathrm e} } \approx 1 836 \cdotp 15267 \,343$

Demonstration
From Mass of Proton, we have:
 * $m_{\mathrm p} \approx 1.67262 \, 19236 \, 9(51) \times 10^{-27}$ kilograms

From Mass of Electron, we have:
 * $m_{\mathrm e} \approx 9.10938 \, 370 \, 15(28) \times 10^{-31}$ kilograms

Hence:
 * $\dfrac {m_{\mathrm p} } {m_{\mathrm e} } \approx 1 836 \cdotp 15267 \,343$
