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:

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 (k_source):1 hp (metric)/ft² = 7916.837 watt per square meter (W/m²)

2. Target SI Bridge (k_target):1 W/cm² = 10000 watt per square meter (W/m²)

Step-by-step substitution for Metric horsepower/square foot → Watt/square centimeter:V(W/cm²) = V(hp (metric)/ft²) × ( 7916.837 / 10000 ) = V(hp (metric)/ft²) × 0.791684

Mathematical FormulaValue in Watt/square centimeter = Value in Metric horsepower/square foot × 0.7916837Direct computational formula applied for standard conversion.

Worked Example

To convert 24 Metric horsepower/square foot (hp (metric)/ft²) to Watt/square centimeter (W/cm²): multiply 24 by 0.791684 to get 19.000409 W/cm². At an industrial engineering scale, 10000 hp (metric)/ft² converts to 7916.837 W/cm².

Inverse check: 1 W/cm² = 1.263131 hp (metric)/ft².
