How to Convert Milliwatt to Foot-pound/second

Converting Milliwatt (mW) to Foot-pound/second (ft·lbf/s) 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 0.000737562 Foot-pound/second, while 1 ft·lbf/s equals 1355.817949 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 ft·lbf/s = 1.355818 watt (W)

Step-by-step substitution for Milliwatt → Foot-pound/second:V(ft·lbf/s) = V(mW) × ( 0.001 / 1.355818 ) = V(mW) × 0.000737562

Mathematical FormulaValue in Foot-pound/second = Value in Milliwatt × 0.00073756215Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 120 Milliwatt (mW) produces 0.0885075 Foot-pound/second (ft·lbf/s). In heavy-duty utility and industrial workloads, 100 mW equals 0.0737562 ft·lbf/s.

Inverse check: 1 ft·lbf/s = 1355.817949 mW.
