How to Convert Pound-foot/second to Dekawatt

Converting Pound-foot/second (lb·ft/s) to Dekawatt (daW) 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 Pound-foot/second equals 0.135582 Dekawatt, while 1 daW equals 7.375621 lb·ft/s.

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 lb·ft/s = 1.355818 watt (W)

2. Target SI Bridge (k_target):1 daW = 10 watt (W)

Step-by-step substitution for Pound-foot/second → Dekawatt:V(daW) = V(lb·ft/s) × ( 1.355818 / 10 ) = V(lb·ft/s) × 0.135582

Mathematical FormulaValue in Dekawatt = Value in Pound-foot/second × 0.13558179Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 2.5 Pound-foot/second (lb·ft/s) produces 0.338954 Dekawatt (daW). In heavy-duty utility and industrial workloads, 5000 lb·ft/s equals 677.908974 daW.

Inverse check: 1 daW = 7.375621 lb·ft/s.
