However, most people do not exactly know what the equation means.

	#Define the variables of the equation. The first step to understanding any equation is to know what each variable stands for. In this case, E is the energy of an object at rest, m is the object's mass, and c is the speed of light in vacuum.[[Image:Understand E=mc2 Step 1 Version 3.jpg|center]]		#Define the variables of the equation.

	#* The speed of light, c is constant in all reference frames and is roughly equal to 3.00x10<sup>8</sup> meters per second. In the context of Einstein's relativity, the c<sup>2</sup> functions more as a unit conversion factor than a constant. As such, it is squared as a result of dimensional analysis - energy is measured in joules, or kg m<sup>2</sup> s<sup>-2</sup>, so adding the c<sup>2</sup> ensures that the relationship between energy and mass is dimensionally consistent.		#* The speed of light, c is constant in all reference frames and is roughly equal to 3.00x10<sup>8</sup> meters per second.
