How to Convert Elementary charge to Franklin

Converting Elementary charge (e) to Franklin (Fr) is a core calculation in Electric Charge, which quantifies the fundamental electrostatic physical property of matter that causes it to experience electromagnetic forces. This calculation bridges modern MKSA metric standards with the historical Gaussian centimetre-gram-second (CGS) electrostatic and electromagnetic framework. In CGS systems, electromagnetic units (such as statvolts, abvolts, dynes, ergs, and gauss) are formulated directly from mechanical dimensions, with electrostatic-to-electromagnetic relations tied to the speed of light in vacuum (c ≈ 2.99792458 × 10¹⁰ cm/s). Exactly 1 Elementary charge translates to 4.803205 × 10⁻¹⁰ Franklin (1 Fr = 2.081943 × 10⁹ e).

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (coulomb (C)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 e = 1.602177 × 10⁻¹⁹ coulomb (C)

2. Target SI Bridge (k_target):1 Fr = 3.335641 × 10⁻¹⁰ coulomb (C)

Step-by-step substitution for Elementary charge → Franklin:V(Fr) = V(e) × ( 1.602177 × 10⁻¹⁹ / 3.335641 × 10⁻¹⁰ ) = V(e) × 4.803205 × 10⁻¹⁰
