How to Convert Milliwatt to Pound-foot/hour

Converting Milliwatt (mW) 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 Milliwatt equals 2.655224 Pound-foot/hour, while 1 lb·ft/h equals 0.376616 mW.

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 lb·ft/h = 0.000376616 watt (W)

Step-by-step substitution for Milliwatt → Pound-foot/hour:V(lb·ft/h) = V(mW) × ( 0.001 / 0.000376616 ) = V(mW) × 2.655224

Mathematical FormulaValue in Pound-foot/hour = Value in Milliwatt × 2.65522374Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 8 mW, applying the conversion factor yields exactly 21.24179 lb·ft/h. At larger operational scale, 480 Milliwatt corresponds to 1274.507394 lb·ft/h.

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