How to Convert Kilowatt to Pound-foot/second

Converting Kilowatt (kW) to Pound-foot/second (lb·ft/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 Pound-foot/second, while 1 lb·ft/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:

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 kW = 1000 watt (W)

2. Target SI Bridge (k_target):1 lb·ft/s = 1.355818 watt (W)

Step-by-step substitution for Kilowatt → Pound-foot/second:V(lb·ft/s) = V(kW) × ( 1000 / 1.355818 ) = V(kW) × 737.562149

Mathematical FormulaValue in Pound-foot/second = Value in Kilowatt × 737.56214928Direct computational formula applied for standard conversion.

Worked Example

Converting 75 kW yields an exact output of 55317.161196 lb·ft/s in Pound-foot/second. Under higher industrial throughput, 10000 kW translates to 7375621.492773 lb·ft/s.

Inverse check: 1 lb·ft/s = 0.00135582 kW.
