Planck units of length, mass, and time are fundamental constants of nature. Tra-ditional constants including Planck’s constant, the gravitational constant, the elementarycharge, and many others are comprised of these three fundamental units. Physics equationsare functions in which maximum potentials defined by the Planck units are reduced byone or more proportionality operators, producing observed quantities of natural phenomena.Natural symmetries constrain the relationships between length, mass, and time, yieldingthe physical dynamics of momentum, action, force, and energy. The Planck units quantifymechanical, gravitational, and electromagnetic properties of the universe and offer a com-mon language for interpreting the standard model interactions. Units associated with theelectromagnetic interaction are translated into units of length, mass, and time, including the coulomb, ampere, volt, tesla, henry, weber, farad, ohm, and siemen.
