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 per square meter (cd/m²)) 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 nt = 1 candela per square meter (cd/m²)
2. Target SI Bridge (ktarget):1 Blondel = 0.31831 candela per square meter (cd/m²)
Step-by-step substitution for Nit → Blondel:V(Blondel) = V(nt) × ( 1 / 0.31831 ) = V(nt) × 3.141593
Mathematical FormulaValue in Blondel = Value in Nit × 3.14159265Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 2.5 Nit (nt) produces 7.853982 Blondel (Blondel). In heavy-duty utility and industrial workloads, 100 nt equals 314.159265 Blondel.

Inverse check: 1 Blondel = 0.31831 nt.
