Hence, a choice to be made when designing a system of natural units is which, if any, instances of 4 π appearing in the equations of physics are to be eliminated via the normalization. Normalizing 4 π G to 1 (and therefore setting G = 1 / 4 π ): Gauss's law for gravity becomes Φ g = −M (rather than Φ g = −4 π M in Planck units).
