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 kcal/(h·m²) = 1.163 watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 J/(s·m²) = 1 watt per square meter (W/m²)
Step-by-step substitution for Kilocalorie (IT)/hour/m² → Joule/second/square meter:V(J/(s·m²)) = V(kcal/(h·m²)) × ( 1.163 / 1 ) = V(kcal/(h·m²)) × 1.163
Mathematical FormulaValue in Joule/second/square meter = Value in Kilocalorie (IT)/hour/m² × 1.16300004Direct computational formula applied for standard conversion.
Worked Example

Converting 15 kcal/(h·m²) yields an exact output of 17.445001 J/(s·m²) in Joule/second/square meter. Under higher industrial throughput, 10000 kcal/(h·m²) translates to 11630.000377 J/(s·m²).
