How to Convert Watt to Pound-foot/hour

Converting Watt (W) 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 Watt equals 2655.223737 Pound-foot/hour, while 1 lb·ft/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 lb·ft/h = 0.000376616 watt (W)

Step-by-step substitution for Watt → Pound-foot/hour:V(lb·ft/h) = V(W) × ( 1 / 0.000376616 ) = V(W) × 2655.223737

Mathematical FormulaValue in Pound-foot/hour = Value in Watt × 2655.2237374Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Watt (W) to Pound-foot/hour (lb·ft/h): multiply 50 by 2655.223737 to get 132761.18687 lb·ft/h. At an industrial engineering scale, 240 W converts to 637253.696976 lb·ft/h.

Inverse check: 1 lb·ft/h = 0.000376616 W.
