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 International table kilocalorie per hour per square metre
The international table kilocalorie per hour per square metre (kcal(IT)/(h·m²)) equals 4186.8/3600 ≈ 1.1633 W/m² (1 kcal(IT) = 4186.8 J; 1 h = 3600 s). The IT variant used in steam engineering, solar thermal collector standards, and process heat calculations. 1 kcal(IT)/(h·m²) ≈ 1.1633 W/m².
