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 (joule (J)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

1. Source SI Bridge (ksource):1 Wh = 3600 joule (J)
2. Target SI Bridge (ktarget):1 MeV = 1.602177 × 10⁻¹³ joule (J)
Step-by-step substitution for Watt-hour → Megaelectron-volt:V(MeV) = V(Wh) × ( 3600 / 1.602177 × 10⁻¹³ ) = V(Wh) × 2.246943 × 10¹⁶

Worked Example

To convert 50 Watt-hour (Wh) to Megaelectron-volt (MeV): multiply 50 by 2.246943 × 10¹⁶ to get 1.123472 × 10¹⁸ MeV. At an industrial engineering scale, 5000 Wh converts to 1.123472 × 10²⁰ MeV.
