What is the energy equivalent of an object with a mass of 1.83 kg?

To determine the energy equivalent of an object, we use the famous equation of Einstein which is E=mc^2 where m is the mass of the object and c is the speed of light (3x10^8 m/s). We calculate as follows:

E = mc^2

E = 1.83 kg (3x10^8 m/s) ^2

E = 1.647x10^17 J
