How to Convert Bougie Décimale to Candle (UK)

Converting Bougie Décimale (bd) to Candle (UK) (candle (UK)) is a core calculation in Luminous Intensity, which measures the wavelength-weighted photometric power emitted by a light source in a direction per unit solid angle. Because Candle (UK) is a broader physical scale than Bougie Décimale, converting from bd to candle (UK) condenses the numerical figure. It takes 1.04 Bougie Décimale to equal a single Candle (UK) (1 bd = 0.961538 candle (UK)). To convert any quantity, multiply by 0.961538 (or divide by 1.04).

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 bd = 1 candela (cd)
2. Target SI Bridge (ktarget):1 candle (UK) = 1.04 candela (cd)
Step-by-step substitution for Bougie Décimale → Candle (UK):V(candle (UK)) = V(bd) × ( 1 / 1.04 ) = V(bd) × 0.961538
Mathematical FormulaValue in Candle (UK) = Value in Bougie Décimale × 0.96153846Direct computational formula applied for standard conversion.
Worked Example

To convert 120 Bougie Décimale (bd) to Candle (UK) (candle (UK)): multiply 120 by 0.961538 to get 115.384615 candle (UK). At an industrial engineering scale, 480 bd converts to 461.538462 candle (UK).

Inverse check: 1 candle (UK) = 1.04 bd.
