How to Convert Foot pound-force/second to Milliwatt

Converting Foot pound-force/second (ft·lbf/s) 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/second equals 1355.817948 Milliwatt, while 1 mW equals 0.000737562 ft·lbf/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 ft·lbf/s = 1.355818 watt (W)

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

Step-by-step substitution for Foot pound-force/second → Milliwatt:V(mW) = V(ft·lbf/s) × ( 1.355818 / 0.001 ) = V(ft·lbf/s) × 1355.817948

Mathematical FormulaValue in Milliwatt = Value in Foot pound-force/second × 1355.81794833Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 75 ft·lbf/s, applying the conversion factor yields exactly 101686.346125 mW. At larger operational scale, 240 Foot pound-force/second corresponds to 325396.3076 mW.

Inverse check: 1 mW = 0.000737562 ft·lbf/s.
