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 (lux (lx)) 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 ph = 10000 lux (lx)
2. Target SI Bridge (ktarget):1 Flame = 43.05564 lux (lx)
Step-by-step substitution for Phot → Flame:V(Flame) = V(ph) × ( 10000 / 43.05564 ) = V(ph) × 232.257609
Mathematical FormulaValue in Flame = Value in Phot × 232.25760899Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 ph, applying the conversion factor yields exactly 8361.273924 Flame. At larger operational scale, 100 Phot corresponds to 23225.760899 Flame.

Inverse check: 1 Flame = 0.00430556 ph.
