Please ensure you have the appropriate definitions.
C = the speed of light in a vacuum (notice the spelling). The speed of light, otherwise, can change depending on the medium it is passing through.

I expect you are not only interested in the deffinition, but also what these thoughts mean when worked out.
There is a trilogy in physics:
E = mc2, m = E/c2, and c2 = E/m. The first shows the basis for the existence of energy. The second is that for the construction of mass. The third is that of a gravitational field - that being a field of physical time.
What you are interested in is the first thought, how/why energy has as its basic composition mass times the speed of light times itself.
First, mass is something that has three, stable dimensions to it. It, also, offers resistance to movement. These are a few ideas that separate mass from other concepts. It is this form of existence that we use when multiplying mass times the speed of light times itself.
When multiplying the speed of light times itself, we form an imaginary grid that whatever passes through it comes out as the speed of light. We can do this same thing with New York Taxis. We can square a taxi of N.Y. and put the Empire State Building through the taxi grid. What goes in the front of the grid is the building, what comes out is all taxis, exactly like the one squared. The number of taxis from the Empire State Building would be in proportion to the mass of the building.
When multiplying mass times the constant squared, we end up with the mass (WHATEVER that mass may be) being converted into values of the speed of light. This means that the speed of light is a form of energy, and we are not just using a number that has no physical meaning to it. It would be possible (on paper) to cube time, and this cube of time to have a particular mass value. This concept is indicated in the concept of c2 = E/m. The value of c2 in our planet is that there is equivalent energy, in gravitational waves, that equal 0.00444 kg/sec. This is the force (energy) required to form earth's gravitational field. Our sun requires the expenditure of 665 lbs/sec in order for the planets to remain about it.

E is energy
m is mass
c is speed of light
basically, the total energy contained in an object is equal to its mass times the speed of light squared (which is a LOT of energy).

E=mass(j)
m=mass kg
c=spped of light 3*10^8

energy (E), in whatever form, and mass (m). In this formula, c², the square of the speed of light in a vacuum.

it is E=Mc^2 ."E" means energy of the system. "M" mass of the system and "c" is the speed of light(constant value)
