c2

When the system as a whole is at rest, the invariant mass is equal to the total energy of the system divided by c2, which is equal to the mass of the system as measured on a scale.

Spacetime is a key component in the step-by-step journey that physicists Brian Cox and Jeff Forshaw take in getting to the bottom of the most famous equation in science, Einstein's E = mc2, which says that mass and energy are the same thing, and you can convert from one to the other using a constant, "c2", a number whose value is equal to the square of the speed of light.
