Dimensionless physical constants

Certain axiological concrete constants, such as the acceleration of ablaze in a vacuum, the accepted gravitational constant, Planck's connected and Boltzmann's connected can be normalized to 1 if adapted units for time, length, mass, charge, and temperature are chosen. The consistent arrangement of units is accepted as the accustomed units. However, not all concrete constants can be normalized in this fashion. For example, the ethics of the afterward constants are absolute of the arrangement of units and have to be bent experimentally:
α ≈ 1/137.036, the accomplished anatomy connected which is the coupling connected for the electromagnetic interaction;
β (or μ) ≈ 1836, the proton-to-electron accumulation ratio. This arrangement is the blow accumulation of the proton disconnected by that of the electron. An akin arrangement can be authentic for any elementary particle;
О±s, the coupling connected for the able force;
αG ≈ 1.75×10−45, the gravitational coupling constant.
