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 candle (UK) = 1.04 candela (cd)
2. Target SI Bridge (ktarget):1 cd (dec) = 1 candela (cd)
Step-by-step substitution for Candle (UK) → Decimal Candle:V(cd (dec)) = V(candle (UK)) × ( 1.04 / 1 ) = V(candle (UK)) × 1.04
Mathematical FormulaValue in Decimal Candle = Value in Candle (UK) × 1.04Direct computational formula applied for standard conversion.
Worked Example

Converting 75 candle (UK) yields an exact output of 78 cd (dec) in Decimal Candle. Under higher industrial throughput, 240 candle (UK) translates to 249.6 cd (dec).

Inverse check: 1 cd (dec) = 0.961538 candle (UK).
