How to Convert Watt to Foot pound-force/hour

Converting Watt (W) to Foot pound-force/hour (ft·lbf/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 Watt equals 2655.223737 Foot pound-force/hour, while 1 ft·lbf/h equals 0.000376616 W.

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 W = 1 watt (W)

2. Target SI Bridge (k_target):1 ft·lbf/h = 0.000376616 watt (W)

Step-by-step substitution for Watt → Foot pound-force/hour:V(ft·lbf/h) = V(W) × ( 1 / 0.000376616 ) = V(W) × 2655.223737
