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 (newton meter (N·m)) 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 pdl·ft = 0.0421401 newton meter (N·m)

2. Target SI Bridge (k_target):1 mN·m = 0.001 newton meter (N·m)

Step-by-step substitution for Poundal foot → Millinewton meter:V(mN·m) = V(pdl·ft) × ( 0.0421401 / 0.001 ) = V(pdl·ft) × 42.140111

Mathematical FormulaValue in Millinewton meter = Value in Poundal foot × 42.14011081Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Poundal foot (pdl·ft) to Millinewton meter (mN·m): multiply 120 by 42.140111 to get 5056.813297 mN·m. At an industrial engineering scale, 100 pdl·ft converts to 4214.011081 mN·m.

Inverse check: 1 mN·m = 0.0237304 pdl·ft.
