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 daW = 10 watt (W)

Step-by-step substitution for Pferdestärke → Dekawatt:V(daW) = V(PS) × ( 735.49875 / 10 ) = V(PS) × 73.549875

Mathematical FormulaValue in Dekawatt = Value in Pferdestärke × 73.549875Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Pferdestärke (PS) to Dekawatt (daW): multiply 120 by 73.549875 to get 8825.985 daW. At an industrial engineering scale, 480 PS converts to 35303.94 daW.

Inverse check: 1 daW = 0.0135962 PS.
