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 candle (int) = 1.019 candela (cd)
Step-by-step substitution for Candle (UK) → Candle (international):V(candle (int)) = V(candle (UK)) × ( 1.04 / 1.019 ) = V(candle (UK)) × 1.020608
Mathematical FormulaValue in Candle (international) = Value in Candle (UK) × 1.02060844Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 12 Candle (UK) (candle (UK)) produces 12.247301 Candle (international) (candle (int)). In heavy-duty utility and industrial workloads, 240 candle (UK) equals 244.946026 candle (int).

Inverse check: 1 candle (int) = 0.979808 candle (UK).
