About Milliwatt per square centimetre
The milliwatt per square centimetre (mW/cm²) equals exactly 10 W/m² (1 mW = 10⁻³ W; 1 cm² = 10⁻⁴ m²). Widely used in photonics, laser safety standards (IEC 60825), and UV dosimetry. Solar irradiance at Earth's surface ≈ 100 mW/cm². 1 mW/cm² = 10 W/m² = 0.001 W/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.
