      There’s a convention in theoretical physics to adopt so-called “natural” units. In the natural system of units, measures of length, time, and mass are chosen so as to make the speed of light and the gravitational constant 1. Or sometimes it’s the speed of light and Planck’s constant.

      Anyhow, this makes the resulting measures of length, time, and mass completely nonsensical to any human scale problem. But it makes physics equations much shorter to write down, because you can drop all of the c’s, G’s, and h-bars and whatnot.

      For example, the famous E = m c^2 becomes E = m. Energy is mass. Voila.
