What is the equivalent energy of 1 amu?

 

 1 Amu's equivalent energy is 931MeV.

According to Einstein's formula, $E=m{c}^2$
Where E is the energy, m is the mass, and c is the speed of light.

We know that, $1 \mathrm{amu}=1.66\times {10}^{27}\mathrm{Kg}$

$\mathrm{c}=3\times {10}^8 \mathrm{m}/\mathrm{s}$

$\mathrm{E}={\mathrm{mc}}^2$

$\mathrm{E}=\left(1.66\times {10}^{-27}\right)\times {\left(3\times {10}^8\right)}^2$

$\mathrm{E}=14.94\times {10}^{-11} \mathrm{J}$
 

converting Joules to eV

$E=\frac{14.94\times {10}^{-11} \mathrm{J}}{1.6\times {10}^{-19}}=931\times {10}^6\mathrm{eV}$

$\mathrm{E}=931\mathrm{MeV}$
