The c² is not central, you can work in a set of units such that the equation is E²=m²+p². If you decide to add a unit for mass, then you naturally need a conversion factor with units of speed.
- 1ris 11y agoThis is the first part of the Explanation. It is indeed E²=m²+p², but the p is the _relativistic_ impulse. For practical proposes you usually want the classical impulse p_0 in this equitation. And is a way easier to see how c shows up in the conversion between these two.
