The distance operator calculates an acceleration due to field potential, such as the gravitational acceleration and force exerted on a second body. The operator is also used to calculate the strength of electrostatic force between electric charges.

The distance operator is a number between 0 and 1 quantifying the inverse number of natural length units over the distance. The operator is the ratio of Planck length to the distance r, which in gravitational formulas can be the surface of a gravitational body or an arbitrary distance from the center of mass.

The distance operator is comparable to the wavelength operator but describes field potentials rather than elementary particles.
