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)

1. Source SI Bridge (ksource):1 hp (metric)/ft² = 7916.842657 watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 cal/(h·cm²) = 11.630003 watt per square meter (W/m²)
Step-by-step substitution for Horsepower (metric)/square foot → Calorie (IT)/hour/square centimeter:V(cal/(h·cm²)) = V(hp (metric)/ft²) × ( 7916.842657 / 11.630003 ) = V(hp (metric)/ft²) × 680.725757
