Question

How many MeV are equivalent to 1 atomic mass unit (u)?

Answer 1

Answer:

1U = 1/12 12C6 (Carbon 12) = 931.478 MeV / c^2

Note:  proton mass = 1.0072766 U = 938.256 Mev/c^2

         electron mass = .000548597 U = .511006 MeV/c^2

Since MeV has units of energy and E = m c^2   then E/c^2 = m
