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 (watt per square meter (W/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 cal/(h·cm²) = 11.63 watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 cal (th)/(h·cm²) = 11.622222 watt per square meter (W/m²)
Step-by-step substitution for Calorie (IT)/hour/cm² → Calorie (th)/hour/cm²:V(cal (th)/(h·cm²)) = V(cal/(h·cm²)) × ( 11.63 / 11.622222 ) = V(cal/(h·cm²)) × 1.000669
