How to Convert Milliwatt to Foot pound-force/hour

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

First-Principles SI Derivation ProofNIST SP 811 / ISO 80000 Compliance

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 mW = 0.001 watt (W)

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

Step-by-step substitution for Milliwatt → Foot pound-force/hour:V(ft·lbf/h) = V(mW) × ( 0.001 / 0.000376616 ) = V(mW) × 2.655224

Mathematical FormulaValue in Foot pound-force/hour = Value in Milliwatt × 2.65522374Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 250 mW, applying the conversion factor yields exactly 663.805934 ft·lbf/h. At larger operational scale, 10000 Milliwatt corresponds to 26552.237374 ft·lbf/h.

Inverse check: 1 ft·lbf/h = 0.376616 mW.
