    Do you wanna try that again?

    A unit of mass useful in particle physics is eV/c^2.

    We start with 1 eV = 1.6×10^-19 J

    Since 1 kg * c^2 = (3×10^8)^2 J,

    J / c^2 = 1 / (3×10^8)^2 kg

    1 eV/c^2 = 1.6×10^-19 / (3×10^8)^2 kg

    1 eV/c^2 = 1.78×10^-36 kg

    1 kg = 5.6095886×10^35 eV/c^2

    So multiply by that conversion factor and keep your desired precision.

      Yes 7.48×10^9 eV / c ^ 2 ! Hackers keep deleting half of your answer.
      Really,
      13.33696×10^-27 kg (5.6095886×10^35 eV/c^2 / kg) = 7481485554 eV/c^2 = 7.48^9 eV/c^2
      Unit propagation will help you catch dimensional mistakes you otherwise wouldn't, always do it.

    Energy and mass are things completely different to each other...
