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 (watt (W)) 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)

2. Target SI Bridge (ktarget):1 ft·lbf/s = 1.355818 watt (W)
Step-by-step substitution for Terawatt → Foot pound-force/second:V(ft·lbf/s) = V(TW) × ( 1 × 10¹² / 1.355818 ) = V(TW) × 7.375621 × 10¹¹
