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 hp (550) = 745.699872 watt (W)

2. Target SI Bridge (k_target):1 PW = 1 × 10¹⁵ watt (W)

Step-by-step substitution for Horsepower (550 ft*lbf/s) → Petawatt:V(PW) = V(hp (550)) × ( 745.699872 / 1 × 10¹⁵ ) = V(hp (550)) × 7.456999 × 10⁻¹³

Mathematical FormulaValue in Petawatt = Value in Horsepower (550 ft*lbf/s) × 7.45699872 × 10⁻¹³Direct computational formula applied for standard conversion.

Worked Example

Converting 75 hp (550) yields an exact output of 5.592749 × 10⁻¹¹ PW in Petawatt. Under higher industrial throughput, 2500 hp (550) translates to 1.86425 × 10⁻⁹ PW.
