How to Convert Kilowatt to Foot pound-force/second

Converting Kilowatt (kW) to Foot pound-force/second (ft·lbf/s) is a core calculation in Power, which measures the rate of energy expenditure, conversion, or work transfer per unit of time. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Kilowatt equals 737.562149 Foot pound-force/second, while 1 ft·lbf/s equals 0.00135582 kW.

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:

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)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 kW = 1000 watt (W)
2. Target SI Bridge (ktarget):1 ft·lbf/s = 1.355818 watt (W)
Step-by-step substitution for Kilowatt → Foot pound-force/second:V(ft·lbf/s) = V(kW) × ( 1000 / 1.355818 ) = V(kW) × 737.562149
Mathematical FormulaValue in Foot pound-force/second = Value in Kilowatt × 737.56214928Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 120 Kilowatt (kW) produces 88507.457913 Foot pound-force/second (ft·lbf/s). In heavy-duty utility and industrial workloads, 10000 kW equals 7375621.492773 ft·lbf/s.
