How to Convert Kilowatt to Pound-foot/hour

Converting Kilowatt (kW) to Pound-foot/hour (lb·ft/h) 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 2655223.737398 Pound-foot/hour, while 1 lb·ft/h equals 3.766161 × 10⁻⁷ 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/h = 0.000376616 watt (W)

Step-by-step substitution for Kilowatt → Pound-foot/hour:V(lb·ft/h) = V(kW) × ( 1000 / 0.000376616 ) = V(kW) × 2655223.737398

Mathematical FormulaValue in Pound-foot/hour = Value in Kilowatt × 2655223.73739816Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 50 Kilowatt (kW) produces 1.327612 × 10⁸ Pound-foot/hour (lb·ft/h). In heavy-duty utility and industrial workloads, 100 kW equals 2.655224 × 10⁸ lb·ft/h.

Inverse check: 1 lb·ft/h = 3.766161 × 10⁻⁷ kW.
