How to Convert Foot-pound/second to Milliwatt

Converting Foot-pound/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/second equals 1355.817949 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/second → Milliwatt:V(mW) = V(ft·lbf/s) × ( 1.355818 / 0.001 ) = V(ft·lbf/s) × 1355.817949

Worked Example

To convert 2.5 Foot-pound/second (ft·lbf/s) to Milliwatt (mW): multiply 2.5 by 1355.817949 to get 3389.544872 mW. At an industrial engineering scale, 1000 ft·lbf/s converts to 1355817.948841 mW.

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