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 per square meter (W/m²)) 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)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 hp (metric)/ft² = 7916.842657 watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 ft·lbf/(min·ft²) = 0.243233 watt per square meter (W/m²)
Step-by-step substitution for Horsepower (metric)/square foot → Foot pound/minute/square foot:V(ft·lbf/(min·ft²)) = V(hp (metric)/ft²) × ( 7916.842657 / 0.243233 ) = V(hp (metric)/ft²) × 32548.421613
