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:

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 PS = 735.49875 watt (W)

2. Target SI Bridge (k_target):1 W = 1 watt (W)

Step-by-step substitution for Pferdestärke → Watt:V(W) = V(PS) × ( 735.49875 / 1 ) = V(PS) × 735.49875

Mathematical FormulaValue in Watt = Value in Pferdestärke × 735.49875Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 36 PS, applying the conversion factor yields exactly 26477.955 W. At larger operational scale, 480 Pferdestärke corresponds to 353039.4 W.

Inverse check: 1 W = 0.00135962 PS.
