How to Convert Hefnerkerze to Pentane Candle (1 cp)

Converting Hefnerkerze (HK) to Pentane Candle (1 cp) (cp (pentane)) 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 Pentane Candle (1 cp) is a broader physical scale than Hefnerkerze, converting from HK to cp (pentane) condenses the numerical figure. It takes 1.10742 Hefnerkerze to equal a single Pentane Candle (1 cp) (1 HK = 0.903 cp (pentane)). To convert any quantity, multiply by 0.903 (or divide by 1.10742).

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 HK = 0.903 candela (cd)
2. Target SI Bridge (ktarget):1 cp (pentane) = 1 candela (cd)
Step-by-step substitution for Hefnerkerze → Pentane Candle (1 cp):V(cp (pentane)) = V(HK) × ( 0.903 / 1 ) = V(HK) × 0.903
Mathematical FormulaValue in Pentane Candle (1 cp) = Value in Hefnerkerze × 0.903Direct computational formula applied for standard conversion.
Worked Example

To convert 50 Hefnerkerze (HK) to Pentane Candle (1 cp) (cp (pentane)): multiply 50 by 0.903 to get 45.15 cp (pentane). At an industrial engineering scale, 480 HK converts to 433.44 cp (pentane).

Inverse check: 1 cp (pentane) = 1.10742 HK.
