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 (candela (cd)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 cp = 0.981 candela (cd)
2. Target SI Bridge (ktarget):1 mcd = 0.001 candela (cd)
Step-by-step substitution for Candlepower (new) → Millicandela:V(mcd) = V(cp) × ( 0.981 / 0.001 ) = V(cp) × 981.000002
Mathematical FormulaValue in Millicandela = Value in Candlepower (new) × 981.00000178Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 250 cp, applying the conversion factor yields exactly 245250.000444 mcd. At larger operational scale, 240 Candlepower (new) corresponds to 235440.000426 mcd.

Inverse check: 1 mcd = 0.00101937 cp.
