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 (th)/(h·cm²) = 11.622217 watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 W/m² = 1 watt per square meter (W/m²)
Step-by-step substitution for Calorie (th)/hour/square centimeter → Watt/square meter:V(W/m²) = V(cal (th)/(h·cm²)) × ( 11.622217 / 1 ) = V(cal (th)/(h·cm²)) × 11.622217
Mathematical FormulaValue in Watt/square meter = Value in Calorie (th)/hour/square centimeter × 11.6222175Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 cal (th)/(h·cm²), applying the conversion factor yields exactly 418.39983 W/m². At larger operational scale, 2500 Calorie (th)/hour/square centimeter corresponds to 29055.54374 W/m².
