How to Convert Kilocalorie (IT)/hour/m² to Calorie (th)/second/cm²

Converting Kilocalorie (IT)/hour/m² (kcal/(h·m²)) to Calorie (th)/second/cm² (cal (th)/(s·cm²)) is a core calculation in Heat Flux Density, which measures the rate of thermal energy transfer radiating or conducting through a unit area per second. Because Calorie (th)/second/cm² is a broader physical scale than Kilocalorie (IT)/hour/m², converting from kcal/(h·m²) to cal (th)/(s·cm²) condenses the numerical figure. It takes 35975.923168 Kilocalorie (IT)/hour/m² to equal a single Calorie (th)/second/cm² (1 kcal/(h·m²) = 2.779637 × 10⁻⁵ cal (th)/(s·cm²)). To convert any quantity, multiply by 2.779637 × 10⁻⁵ (or divide by 35975.923168).

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 cal (th)/(s·cm²) = 41840 watt per square meter (W/m²)
Step-by-step substitution for Kilocalorie (IT)/hour/m² → Calorie (th)/second/cm²:V(cal (th)/(s·cm²)) = V(kcal/(h·m²)) × ( 1.163 / 41840 ) = V(kcal/(h·m²)) × 2.779637 × 10⁻⁵
Mathematical FormulaValue in Calorie (th)/second/cm² = Value in Kilocalorie (IT)/hour/m² × 2.7796368 × 10⁻⁵Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 15 kcal/(h·m²), applying the conversion factor yields exactly 0.000416946 cal (th)/(s·cm²). At larger operational scale, 100 Kilocalorie (IT)/hour/m² corresponds to 0.00277964 cal (th)/(s·cm²).
