About Erg per second per square centimetre
The erg per second per square centimetre (erg/(s·cm²)) equals exactly 10⁻³ W/m² in SI (1 erg = 10⁻⁷ J; 1 cm² = 10⁻⁴ m²). The CGS irradiance unit used in classical electromagnetic theory, astrophysics, and older radiation physics literature. Numerically equal to the milliwatt per square metre. 1 erg/(s·cm²) = 10⁻³ W/m² = 1 mW/m².
About Thermochemical kilocalorie per hour per square centimetre
The thermochemical kilocalorie per hour per square centimetre (kcal(th)/(h·cm²)) equals 4184/(3600×10⁻⁴) ≈ 11622 W/m² (= 10⁴ × kcal(th)/(h·m²)). A high-flux variant of the metric heat flux unit found in older combustion engineering and furnace design references. 1 kcal(th)/(h·cm²) ≈ 11622 W/m².
