This paper introduces a new theoretical and empirical framework that precisely defines fundamental physical quantities such as mass, length, frequency as quantum intervals. Secondary units of electric current, voltage, resistance, charge squared, and magnetic flux are herein redefined. The reason for the fine-structure constant (α), Newton's Gravitational Constant (G), are defined by equations describing wave-particle duality, field and flux. The core of this work utilizes a series of algebraic equations to elucidate the true underlying physical significance of these terms. Empirical equations depict the reason for electromagnetism measured as amperes of electric current flowing through a copper wire. The analysis describes Newton's Gravitational Constant (G) as intrinsic to the metrology of electromagnetism within the copper conductor. It is demonstrated that G plays a critical, unifying role in the subatomic dynamics governing electric current flow, suggesting a fundamental link between gravity and electromagnetism that extends from the subatomic realm to galactic scales.
