About Milliwatt per square metre
The milliwatt per square metre (mW/m²) equals 10⁻³ W/m². Relevant in geothermal surveys: global average continental heat flux ≈ 65 mW/m², oceanic ≈ 101 mW/m². Used in building physics for quantifying very small heat leakage through ultra-high-performance insulation. 1 mW/m² = 10⁻³ W/m² = 1 erg/(s·cm²).
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.
