Governing Physical Laws & Axiomatic Formulations

Under ISO 80000 principles, every unit conversion in this faculty is derived through exact mathematical pathways governing the underlying physical law.

Avogadro Molar Substance Definition

n = \frac{N}{N_A}, \quad N_A = 6.02214076 \times 10^{23} \text{ mol}^{-1}

Fundamental SI quantity establishing amount of substance N in moles (mol) via the exact Avogadro constant.

Brake Specific Fuel Consumption (BSFC)

\text{BSFC} = \frac{\dot{m}_f}{P_{\text{shaft}}} = \frac{\text{Mass Flow of Fuel}}{\text{Shaft Power Output}}

Internal combustion engine fuel efficiency metric with coherent SI dimension [L⁻² T²] (kg/J or g/(kW·h)).

First Law Energy-Work Conservation

\Delta U = Q - W, \quad W = \int P \, dV

Thermodynamic work and heat equivalence, defining Joule (J = N·m = kg·m²/s²), BTU, and calorie conversions.
