An analogous ratio can be defined for any elementary particle; αs ≈ 1, a coupling constant characterizing the strong nuclear force; αG ≈ 1.75 × 10−45, the gravitational coupling constant which is the square of the ratio of the mass of the electron to the Planck mass, which characterizes the magnitude of the gravitational interaction between electrons.
