We can calculate the value of Atomic Mass Unit(u) in terms of Energy by using the Einstein's mass-energy equation:$E=m{c}^{2}$.

Now, the absolute mass of Atomic Mass unit is $1.66\times{10}^{-27}$kg and the exact value of speed of light is $2.998\times{10}{8}$m/s. So, by putting these values in Einstein's equation, we will have:

$E=(1.66\times{10}^{-27}){(2.998\times{10}^{8})}^{2}$By solving this approximately we will get:

1 Atomic Mass Unit = $1.492\times{10}^{-10}$J

Thus, 1 Atomic Mass Unit (u) is equivalent to$1.492\times{10}^{-10}$of enegy. We can convert this energy from Joules to Million Electron Volts (MeV) by using the relation:$1.602\times{10}^{-13}$J=1 MeV.

This will give us the following value of Atomic Mass Unit:

1 Atomic Mass Unit = 931 MeV.

Thus, 1 Atomic Mass Unit (u) is equivalent to 931 MeV of enegy.
