How to Convert Foot pound-force/hour to Milliwatt

Converting Foot pound-force/hour (ft·lbf/h) to Milliwatt (mW) 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 Foot pound-force/hour equals 0.376616 Milliwatt, while 1 mW equals 2.655224 ft·lbf/h.

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 ft·lbf/h = 0.000376616 watt (W)

2. Target SI Bridge (k_target):1 mW = 0.001 watt (W)

Step-by-step substitution for Foot pound-force/hour → Milliwatt:V(mW) = V(ft·lbf/h) × ( 0.000376616 / 0.001 ) = V(ft·lbf/h) × 0.376616

Mathematical FormulaValue in Milliwatt = Value in Foot pound-force/hour × 0.3766161Direct computational formula applied for standard conversion.

Worked Example

To convert 24 Foot pound-force/hour (ft·lbf/h) to Milliwatt (mW): multiply 24 by 0.376616 to get 9.038786 mW. At an industrial engineering scale, 10000 ft·lbf/h converts to 3766.160968 mW.

Inverse check: 1 mW = 2.655224 ft·lbf/h.
