I E=mc^2 fact check

  1. Aug 1, 2018 #1
    I am doing an article that includes a brief explanation of Einstein's basic equation, and want to check my work. As I understand it, the equation is e(energy in Joules)=m(in grams)×speed of light in meters/second squared(9×10 to the 16th). Is this reasonably correct? Thanks.

    Almost. In SI units m is in kilograms.

    Edit: V50 for the win!

    Kilograms it is. Thanks to both for the double-check!
